If you’re running a WordPress site, you may encounter the 500 Internal Server Error, which can be frustrating and difficult to diagnose. This error can occur due to a variety of reasons, such as plugin conflicts, server issues, or corrupted files. In this article, we’ll walk you through how to fix the 500 Internal Server Error in WordPress.

Step 1: Check for the cause of the error
The first step in fixing the 500 Internal Server Error is to determine the cause of the error.
You can check the error logs to see if there are any specific error messages that can help identify the issue.
In some cases, the error may be caused by a plugin conflict or a theme issue.
Step 2: Deactivate plugins
One common cause of the 500 Internal Server Error is a plugin conflict. To check if a plugin is causing the issue, deactivate all plugins and check if the error still occurs. If the error disappears, reactivate your plugins one by one until you find the plugin that is causing the issue.
You can deactivate plugins from your wordpress manager in your cpanel of your hosting provider. This way you don’t even have to be logged in to disable the wordpress plugins that might be causing your site to break.

Step 3: Switch to a default theme
If deactivating plugins does not resolve the issue, the next step is to switch to a default WordPress theme that is up to date, such as Twenty Twenty-Three. If the error disappears after switching the theme, the issue may be caused by your previous theme.
Sometimes even deactivated theme can cause a conflict in code, which takes down your entire site.
Remember: You can also use the debug mode in your wordpress management overview like shown in the image below.

Step 4: Increase PHP memory limit

If your website has a large number of plugins or a high traffic volume, the 500 Internal Server Error may be caused by the PHP memory limit. To increase the PHP memory limit, you can edit the wp-config.php file or contact your hosting provider.
If you have access to a CPanel you can change these settings in the Multi PHP INI Editor like shown below.

Step 5: Fix corrupted files
If the 500 Internal Server Error is caused by corrupted files, you can try reinstalling WordPress.
Before doing so, create a backup of your website to avoid losing any data.
Again this is easy with Cpanel filemanager.
Just upload the latest wordpress installation file to your root and unpack ..
If all this doesn’t work , then check your PHP settings.
You might be running an outdated php version on your server.
Which leads us to step number 6.
Step 6: Contact your hosting provider
If the above steps do not resolve the issue, the error may be caused by server issues. Contact your hosting provider’s support team and provide them with the error logs to help identify and resolve the issue.
If you can even check the error log before you submit a ticket.
Step 7: Troubleshoot
further If the error still persists after following the above steps, you can try further troubleshooting by disabling your .htaccess file, checking file permissions, or increasing the maximum execution time.
In conclusion, the 500 Internal Server Error in WordPress can be caused by various factors, but following the above steps can help diagnose and fix the issue. If you’re still unable to resolve the error, seek assistance from a professional WordPress developer or agency.
