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.

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

  • Use an FTP client or cPanel.
  • 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.

As FTP is known as a File Transfer Protocol which is an internet protocol and is an easy, fast and secure way of transmitting the information between the server and the client. As by using FTP, you can access these files from your computer and changes can be made to the server automatically.

Whereas cPanel known as control panel is a web hosting panel which gives a website all the automation tools to simplify the process of hosting a website and provides a graphical user interface to the WordPress.

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.

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.

Re-uploading Core Files

If the plugin option didn’t fix the internal server error, then it gives the benefit re-uploading the wp-admin and wp-includes folder from a fresh WordPress install. This will not delete any of your information. But may easily fix the problem in case any file was corrupted. See the step to proceed-
