How to Fix WordPress 500 Error?

When faced with the WordPress HTTP Error 500, there are several steps you can take to resolve the issue. Here are some proven methods to fix the WordPress 500 Error:

Check for Plugin or Theme Issues

Deactivate all plugins and switch to a default theme to identify any conflicting elements. Gradually reactivate plugins and themes to isolate the problematic ones.

Repair the .htaccess File

Access your website’s root directory via FTP, rename the .htaccess file, and regenerate a new one by saving the Permalinks settings in your WordPress dashboard.

Increase PHP Memory Limit

Edit the wp-config.php file and add the code `define(‘WP_MEMORY_LIMIT,’ ’64M’);` to increase the PHP memory limit, allowing your website to handle larger requests.

Verify Server File Permissions

Ensure that the file and folder permissions on your server are set correctly. Incorrect permissions can cause the HTTP Error 500. Set the appropriate permissions using an FTP client or by contacting your hosting provider.

Update WordPress Core, Plugins, and Themes

Outdated versions of WordPress core, plugins, or themes can sometimes lead to conflicts and trigger HTTP Error 500. Keep your WordPress installation, plugins, and themes up to date to ensure compatibility and stability.

Disable Recently Installed Plugins or Themes

Restore a Previous Backup

If you have a recent website backup, consider restoring it to a point before the HTTP Error 500 occurred. This can help revert any changes that might have caused the error.

Contact Your Hosting Provider

If you have tried the above steps and cannot fix the HTTP Error 500, it is advisable to reach out to your hosting provider’s support team. They can investigate the issue from the server side and provide specific guidance to resolve the error.
