The 500 Internal Server Error is one of the most common panic-inducing “I’ve broken everything!” catch-all errors in WordPress that can literally mean anything.
Most commonly 500 Internal Server Errors occurs due to misconfiguration of ‘.htaccess’ file. So, you may want to rename it like ‘.htaccess_bk’. Usually, this folder is present in public_html folder of your file manager. As it is a hidden file you need to select the option called show hidden files in settings of your file manager. Check the permissions for ‘.htaccess’ mostly it is 644.
Check WordPress Plugins
Another reason for 500 Internal Server Error, it may cause due to WordPress plugins. If you are getting this error after activating any new plugin, I recommend you to deactivate the new plugin and reload your website.
There might be a case in which you cannot access the WordPress dashboard. Here you can use FTP or cPanel to navigate to the ‘plugins’ folder to the wp-content folder.
Check php memory limit
Plugins,scripts, and themes often utilize huge memory. All you need to do is to add following line of code “memory_limit = 64M” in your php.ini file present in your home directory.
