What is the 500 Internal Server Error?

You will find some vague definitions of the WordPress 500 error. There is no indication as to what has caused the error. The only thing that is for sure is that something has gone wrong with some operation on the WP site’s end. In the case of WordPress, this may mean that a piece of code, which is a component of a plugin or a theme, did something wrong, and now you have a crashed server.

However, you don’t need to scratch your head as we have some fixes for you:

The Top Fixes for the 500 Internal Server Error

Switch to debugging

Whenever WordPress shows you a server error or a white screen of death, it is recommended to turn on debugging. Although turning on debugging may not fix the issue, it can provide you with a deep insight into the whole situation. 

To turn on debugging, you need to edit your file named wp-config.php. Once you get access to this file, look for WP_DEBUG, and if you find that, you can set it as “true.” If you don’t see the WP_DEBUG file, then you will have to create one yourself. In either case, you need to have a coding line that looks like this:

Define (“WP_DEBUG”, true);

Reload your site now and check if any changes have happened. If luck is with you, the WordPress internal server error will disappear and can be replaced with any other error. The replaced error might tell you about the actual issue. In this case, trace the location of the error. If the location is within the plugin folder, disable it, and the error will be removed.

If turning on debugging doesn’t remove the 500 internal server error, it’s better to keep it turned on until the issue gets resolved. During the process, your developers will get insight. Always remember to turn off debugging when the problem is fixed and the website maintenance is done.
