1. Understanding The 500 Internal Server Error

The 500 Internal Server Error is a common issue that can occur on any website, not just WordPress sites. It is an HTTP error code that indicates the server encountered an unexpected problem, preventing it from fulfilling the request.

In simpler terms, it’s a generic error message displayed when the server doesn’t have a more specific error to show. This can happen due to various reasons, such as misconfigured settings, server overload, or conflicts with plugins or themes.

When this error occurs, the appearance of the error page may differ depending on the web server software (Apache or Nginx) your website uses and the browser you are using.

In summary, the 500 Internal Server Error is a general error message that indicates something went wrong on the server side, causing the website to malfunction temporarily.

The 500 Internal Server Error might appear differently based on the web server (like Nginx) and the browser you’re using, such as Google Chrome.

Sometimes, if Google Chrome can’t find an error page to display, it may show a simple error message, making it look different from the usual error page.

In simple terms, the appearance of the 500 Internal Server Error can vary depending on your web server and browser. If Google Chrome can’t locate a specific error page, it will show a basic error message instead.

For beginners, encountering the 500 Internal Server Error can indeed be highly frustrating. Unlike specific error messages, this error provides no clue or direction on how to resolve it promptly.

An analogy to understand this situation is like asking a doctor to fix your pain without indicating the location of the pain. Without knowing the root cause, finding a solution can be challenging.

However, if we familiarize ourselves with the common triggers of this error, we can systematically address them one by one. By methodically troubleshooting the potential causes, we can resolve the error without causing any additional issues. This approach allows us to fix the problem step by step and restore the website’s functionality with confidence.

Identifying Causes of The Internal Server Error in WordPress

The Internal Server Error in WordPress can have several causes. Some common triggers include a corrupt .htaccess file, poorly coded plugins, or issues with the active WordPress theme.

Additionally, the error may occur due to limitations in the PHP memory limit or corruption in core WordPress files.

In certain cases, the internal server error may only affect the WordPress admin area, while the rest of the site functions normally.

To resolve this error, it’s essential to follow a systematic troubleshooting process. In the upcoming sections, we will explore how to troubleshoot and resolve the Internal Server Error in WordPress effectively.

Fixing The 500 Internal Server Error in WordPress

Before you embark on the troubleshooting process, it is crucial to have a complete WordPress backup of your website ready.

If you have access to the WordPress admin area, you can utilize a reliable WordPress backup plugin like Duplicator to create a comprehensive backup of your website.

However, if you lack access to the WordPress admin area, you can manually generate a WordPress backup using phpMyAdmin and an FTP client.

Once you have a backup in place, follow these steps to effectively troubleshoot and resolve the internal server error on your website.

Clear WordPress and Browser Cache

Sometimes, browsers and WordPress caching plugins may inadvertently store a cached copy of an error page, leading to the persistence of the internal server error.

To address this issue effectively, the simplest approach is to clear your browser cache. This action will help ensure that your browser fetches the most recent version of the web page and can potentially resolve the internal server error.

After clearing your browser cache, if you have access to the WordPress admin area of your website, you can proceed to empty the WordPress cache by visiting your caching plugin’s settings page.

For more detailed instructions on how to clear the WordPress cache, you can refer to our tutorial that provides step-by-step guidance on this process.

Checking for Corrupt .htaccess File

The .htaccess file is a crucial server configuration file utilized by WordPress to manage redirects and other settings.

A common culprit behind the internal server error is a corrupt .htaccess file.

The simplest solution to fix this issue is to navigate to the WordPress admin area’s “Settings” » “Permalinks” page and click on the ‘Save Changes’ button without making any modifications. This action will regenerate the .htaccess file, potentially resolving the internal server error.

After attempting to regenerate or update the .htaccess file through the WordPress admin area, you should check if the internal server error has been resolved.

In case the error persists, it may be due to WordPress being unable to generate or write to the .htaccess file. This can happen due to file and directory permissions.

• To address this, you can manually replace the .htaccess file. Follow these steps:
• Login to your website using FTP or the File Manager app in your hosting account control panel.

Locate the main .htaccess file in the same directory where you find folders like wp-content, wp-admin, and wp-includes.

• Right-click on the .htaccess file and rename it to .htaccess_old. This action keeps the file as a backup, but WordPress won’t recognize it.

By performing these steps, you can troubleshoot the issue and potentially resolve the internal server error.

After renaming the previous .htaccess file, the next step is to create a new .htaccess file.

• Follow these steps to create a new .htaccess file inside your site’s root folder:
• Navigate to your site’s root folder using your FTP client or File Manager app.

Right-click within the root folder and select the ‘Create new file’ option.

By creating a new .htaccess file, you are setting the stage for WordPress to generate a fresh and properly configured .htaccess file.

Name the newly created file as .htaccess and click OK to save it.

At this point, the .htaccess file is empty, and you need to add the default WordPress rewrite rules to it.

To do this, right-click on the .htaccess file and then select View/Edit in your FTP client or File Manager app. This will open the file in a text editor, allowing you to add the necessary WordPress rewrite rules.

Certainly! Here is the code that you need to copy and paste inside the empty .htaccess file:

# BEGIN WordPress

RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ – [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]

# END WordPress

Indeed! The provided code is the default rule set used by WordPress. After pasting the code into the .htaccess file, remember to save your changes and upload the file back to the server.

Once you’ve done this, visit your website to check if the internal server error has been resolved. If it’s fixed, congratulations! You’ve successfully resolved the internal server error.

However, before you proceed with other tasks, it’s essential to go to the “Settings” » “Permalinks” page in the WordPress admin area and click the save button without making any changes. This step will regenerate the .htaccess file with the appropriate rewrite rules, ensuring that your post pages don’t return a 404 error.

By following these steps, you should be able to address the internal server error and have your WordPress website running smoothly again.

Increasing the PHP Memory Limit

Sometimes, the internal server error can occur if a script is consuming all the PHP memory limit. Increasing the PHP memory limit is a potential solution, but it requires careful attention, especially for beginners. Making mistakes in WordPress core files can lead to site issues.

To increase the PHP memory limit, follow these steps:

• Connect to your WordPress website using an FTP client or the File Manager app in your hosting account control panel.
• Locate the wp-config.php file in the main folder of your website.
• Right-click on wp-config.php and select ‘Download’ to create a backup of the file.
• Next, right-click on wp-config.php again and select ‘View/Edit’ to open the file in a text editor.

By performing these steps, you can proceed to increase the PHP memory limit in the wp-config.php file without disrupting your site.

Inside the wp-config.php file, you need to add the following code just above the line that reads ‘That’s all, stop editing! Happy publishing’.

define(‘WP_MEMORY_LIMIT’, ‘256M’);

This code will increase the PHP memory limit to 256MB. After adding the code, save the wp-config.php file and upload it back to your server. This should help resolve the internal server error caused by PHP memory limit issues.

If you encounter the internal server error in WordPress, it can be a frustrating experience, especially for beginners. The error message does not provide specific information, making it challenging to pinpoint the exact cause.

To troubleshoot and fix the 500 internal server error, it’s crucial to have a complete backup of your WordPress website. If you have access to the WordPress admin area, use a backup plugin like Duplicator to create a backup. For those without access, manually create a backup using phpMyAdmin and an FTP client.

Once you’ve backed up your site, you can start troubleshooting by following these steps:

1. Clear your browser cache to rule out cached error pages causing the issue.
2. Check the .htaccess file for corruption. Easily do this by visiting the Settings » Permalinks page in the WordPress admin area and clicking the ‘Save Changes’ button without making any changes. WordPress will attempt to regenerate or write a new .htaccess file.
3. If the .htaccess file is the culprit, create a new one with the default WordPress rewrite rules. Save this file and upload it to your server.
4. In case the internal server error persists, you may need to increase the PHP memory limit. Edit the wp-config.php file and add the following line just above the ‘That’s all, stop editing! Happy publishing’ line: define(‘WP_MEMORY_LIMIT’, ‘256M’);.
5. For specific instances of the internal server error while logging in to the WordPress admin or uploading images, create a blank text file named php.ini and add memory=256MB to it. Upload this file to the /wp-admin/ folder using FTP.

Remember, increasing the memory limit may temporarily fix the issue, but identifying the underlying cause is crucial. Reach out to your web hosting company for assistance in checking server logs to diagnose the exact problem.

If increasing the PHP memory limit does not resolve the issue, further troubleshooting steps will be necessary.

Deactivate All WordPress Plugins

If the previous solutions didn’t resolve the issue, the internal server error is likely caused by a specific plugin or a combination of plugins conflicting with each other.

To identify the problematic plugin, you can deactivate all WordPress plugins from the WordPress admin area:

1. Go to the Plugins page in your WordPress admin dashboard.
2. Click on the “Deactivate” option that appears when you hover over each plugin.
3. Deactivate all the plugins on your website.

Once you have deactivated all the plugins, check if the internal server error is resolved. If the error is gone, it confirms that one of the plugins was causing the issue.

Now, to pinpoint the problematic plugin, reactivate each plugin one by one, checking the website after each reactivation. When the internal server error reoccurs, you’ll know that the recently activated plugin is the culprit.

You can then either find an alternative plugin to replace the problematic one or reach out to the plugin’s developer for support and assistance in resolving the compatibility issue.

If deactivating all plugins doesn’t fix the error, other troubleshooting steps will be necessary.

If you’re unable to access the WordPress admin area, you can still deactivate all WordPress plugins using FTP:

1. Connect to your WordPress website using an FTP client or the file manager app in your hosting account control panel.
2. Navigate to the /wp-content/ folder.
3. Rename the “plugins” folder to “plugins.deactivated.”

By renaming the plugins folder, WordPress won’t be able to locate the plugins, effectively deactivating all of them.

Now, check your website to see if the internal server error has been resolved. If the error is gone, it indicates that one of the plugins was causing the issue.

To identify the problematic plugin, follow these steps:

1. Rename the “plugins.deactivated” folder back to “plugins” to restore all your plugins.
2. Your plugins will be restored but still deactivated.
3. Activate each plugin one by one, and after activating each plugin, visit your website to see if the internal server error returns.
4. Continue this process until you find the plugin that causes the error.

Once you identify the problematic plugin, you can either find an alternative or reach out to the plugin’s developer for assistance.

If deactivating all plugins didn’t fix the internal server error, there might be other underlying causes that require further troubleshooting.

Switch to a Default WordPress Theme

To determine if the internal server error is caused by your WordPress theme, you should switch to a default WordPress theme. Follow these steps:

1. If you can access the WordPress admin area, go to “Appearance” » “Themes” page.
2. Look for a default theme that comes pre-installed with WordPress (e.g., Twenty Twenty-One, Twenty Twenty, etc.).
3. Hover over the default theme and click the “Activate” button to switch to the default theme.

Now, visit your website to see if the internal server error is resolved. If the error is gone, it means the issue was related to your previous theme.

If switching the theme fixes the error, you may need to review your previous theme’s code or check for any recent updates or conflicts with plugins.

Remember to keep your default theme activated for now, and you can switch back to your original theme once the issue is resolved or use a different theme altogether if needed.

If changing the theme didn’t fix the internal server error, there might be other factors causing the problem that require further investigation.

If your WordPress website doesn’t have a default theme installed, you can follow these steps to switch to a default theme:

1. If You Have Access to the WordPress Admin Area:

• Go to “Appearance” » “Themes” page in your WordPress admin area.
• Click the “Add New” button at the top.
• Search for a default theme like “Twenty Twenty-Three”, “Twenty Twenty-Two”, etc.
• Install and activate the default theme.

2. If You Don’t Have Access to the WordPress Admin Area:

• Connect to your WordPress website using an FTP client.
• Navigate to the /wp-content/ folder and locate the “themes” folder.
• Download the “themes” folder to your computer as a backup.
• Delete the “themes” folder from your website.
• Create a new empty folder and name it “themes”.
• Visit the WordPress themes directory at wordpress.org/themes/.
• Find and download a default WordPress theme (e.g., Twenty Twenty-Three) to your computer.
• Upload the downloaded default theme folder to the newly created “themes” folder on your website using FTP.

Once you have installed the default theme, visit your website to see if the internal server error is resolved. If the error is gone, it indicates that the issue was related to your previous theme.

Remember to keep the default theme activated for now, and you can switch back to your original theme once the issue is resolved or use a different theme altogether if needed.

To switch to a default WordPress theme, follow these steps:

1. Download and Extract Default Theme:

• Visit the WordPress themes directory at wordpress.org/themes/.
• Find a default WordPress theme (e.g., Twenty Twenty-Three) and click on it.
• Click the “Download” button to save the theme as a zip file to your computer.
• Locate the downloaded zip file and unzip it. Windows users can right-click and select “Extract All,” while Mac users can double-click on the zip file.

2. Upload Default Theme Using FTP:

• Connect to your WordPress website using an FTP client or File Manager app in your hosting control panel.
• Navigate to the /wp-content/themes/ folder on your website.
• Upload the entire folder of the default theme you extracted to the /wp-content/themes/ folder on your website.

3. Activate the Default Theme:

• Once the default theme is uploaded, WordPress will automatically detect it.
• Go to “Appearance” » “Themes” page in your WordPress admin area.
• You will see the newly uploaded default theme listed there.
• Hover over the default theme and click on the “Activate” button to switch to the default theme.
• After activating the default theme, visit your website to see if the internal server error is resolved. If the error is gone, it means that the issue was related to your previous theme.

Remember, the default theme might look different from your previous theme, but it will help you identify if the issue is theme-related or not. You can switch back to your original theme once the issue is resolved, or you may consider using a different theme that is compatible with your website. If the error persists, there are still other troubleshooting steps you can take to fix it.

Re-uploading Core WordPress Files

If the previous attempts to fix the internal server error didn’t work, you can try re-uploading the /wp-admin/ and /wp-includes/ folders from a fresh WordPress installation. This process will not remove any of your data but may resolve the issue if any file was corrupted.

1. Visit the WordPress.org website and click on the Download button to get the latest WordPress zip file.
2. Extract the downloaded zip file, and you will find a wordpress folder.
3. Connect to your WordPress website using an FTP client.
4. Navigate to the root folder of your website, where you can see wp-admin, wp-includes, and wp-content folders.
5. In the FTP client, open the wordpress folder on your computer.
6. Select all the files inside the wordpress folder and upload them to your website’s root folder.
7. The FTP client may prompt you to overwrite files. Choose ‘Overwrite’ and then select ‘Always use this action’.
8. The FTP client will now replace your old WordPress files with fresh copies from the new installation.

If the internal server error was caused by corrupted WordPress files, this step should resolve the issue. You can now visit your website to check if the error is fixed.

Enabling Debug Logs in WordPress

WordPress provides a built-in system to keep logs for debugging purposes. To enable this feature, you can use the WP Debugging plugin. If you’re not sure how to install a WordPress plugin, you can refer to our guide on the topic.

Once the plugin is activated, it will automatically enable debugging logs on your WordPress website.

In case you don’t have access to the admin area of your WordPress website, you can still turn on debugging by adding the following code to your wp-config.php file:

define( ‘WP_DEBUG’, true);
define( ‘WP_DEBUG_LOG’, true);

After enabling debug logs, you can view the logs by using an FTP client to navigate to the /wp-content/ folder.
