500 Internal Server Error
The 500 Internal Server Error is a very broad HTTP status code that indicates that something has gone wrong on the website’s server, but the server is unable to provide more precise information about the issue. Some causes of a 500 internal server error include corrupted or broken .htaccess file, a permissions error, third-party plugins, or themes with errors.
Suggested 500 Internal Server Error Solutions
- Refreshing the page.
- Come back later.

If the website is yours, you can also try this solution:
- Deactivating a plugin or theme. Newly installed software, add-ons, or third-party scripts may be causing the internal server problem, try (carefully) deactivating or removing each of your software add-ons one at a time.
- Try using the WPDebugging plugin to identify the problem.
- Re-check PHP configuration.
- Re-check .htaccess file.
