Check .htaccess file

The .htaccess(hypertext Access file) is the configuration file of a website. This configuring file used to run Apache Web Server software. Any alteration in this file can cause an error.

If 500 Internal Server Errors is caused due to misconfiguration of ‘.htaccess’ file then rename the file like ‘.htaccess_bk’. Generally, this folder is present in the public_html folder of your file manager.

As it is a hidden file, So it might be possible that you are not able to find it. Here you need to choose the option called show hidden files in settings of your file manager. Check the permissions for ‘.htaccess’ usually, it is 644.

Once its done find the file and rename it. Reload your site and check the 500 internal error is resolved or not. If this technique doesn’t work for you then move on to another way.

Check PHP version

If you are using PHP version above 5.3 and your .htaccess file consists of “register_globals = on” line you need to remove it and reload your site. As register globals only support till PHP version 5.3.

Check WordPress Themes

  • Next, open the ‘themes’ folder and rename the folder containing all files which access the theme which is activated.
  • It will deactivate the current theme and the default theme will be activated automatically.
  • At last, reload the website.

Increasing the PHP Memory Limit

Sometimes this Internal server error can occur if you are exhausting your PHP memory limit. If you are seeing the internal server error when you trying to login to your WordPress admin or uploading an image in your wp-admin, then try to increase the memory limit by following the steps given below

We recommend that you ask your WordPress web hosting company to look into the server logs to help you find the exact problem.

Deactivate all Plugins

If none of the above-given solutions worked for you, then this error is being caused by a precise plugin. It can be possible that it is a combination of plugins that are not playing well with each other. So, you have to deactivate all WordPress plugins at once.
