Perhaps the most confusing WordPress error that a beginner may come across is “Internal Server Error”, or sometimes “500 Internal Server Error”.
This error usually appears when there is something wrong, but the server is unable to identify where the problem is. Since the error message does not indicate where you should look for the error, it is pretty much up to you to figure this out.
WP Beginner has compiled a list of solutions that you can try and one of them will help you resolve it. See how to fix internal server error in WordPress.
WordPress introduced a fatal error protection feature in WordPress 5.2. This feature displays a simple error message stating that “This site is experiencing technical difficulties”.
For full details, WordPress then sends an email notification on your WordPress admin email address. This email message contains a link to access the backend and attempt to fix the error.
This error message can be triggered by any of the fatal errors mentioned in this article. If you don’t have access to the admin email or can’t get WordPress emails then it becomes harder to find out what error is occurring.
The easiest way to fix this is to make sure that your WordPress admin email address is correct and that you can receive WordPress notification emails.
