500 Internal Server Error on WordPress Site
Category: Web Applications
The 500 Internal Server Error is a common issue in WordPress that can be caused by a variety of factors such as corrupt files, database errors, or plugin conflicts. Below are some methods to troubleshoot and fix this error.
1. Try Reloading the Page
This may seem simple, but one of the first things you should try is refreshing the page (F5 or Ctrl + F5). Sometimes, the error resolves itself.
2. Enable PHP Error Display
Go to Advanced -> PHP Settings in your control panel and enable error display. This can help you identify the issue more clearly.
Check your site's PHP version settings and refresh the page to display the underlying error.
3. Enable WordPress Debugging Mode
Edit your wp-config.php file and enable debugging by setting WP_DEBUG
to true:
define( 'WP_DEBUG', true );
This will log errors and help pinpoint the source of the 500 error.
4. Error Establishing a Database Connection
If the error is related to your database connection, verify your login credentials in the wp-config.php file.
Check for any incorrect database login details that might be preventing WordPress from connecting to your database.
5. Check Plugins and Themes
Plugins and themes can cause 500 errors. Disable all plugins and see if the issue is resolved. If it is, re-enable them one by one to find the faulty plugin or theme.
If you can't access the admin dashboard, rename the plugins folder using the File Manager.
Note: Always ensure your plugins, themes, and WordPress core are up to date. Check that your PHP version is supported by WordPress.
