The page isn’t working, site is currently unable to handle this request. HTTP ERROR 500

While accessing WordPress site's sub-links and back-end (WordPress admin dashboard ) I was getting error message as -

"The page isn’t working, site is currently unable to handle this request. HTTP ERROR 500".

Below are the Error log - ( tail -f /usr/local/apache/logs/error_log | grep IP address )

Solution :-

1. If there is PHP selector in your cPanel then you can try to update the PHP version from cPanel >> Select PHP version >> Save.

2. Check the '.htaccess file', if you'll find any code which is other than WordPress's default '.htaccess' file code then please comment that code.

3. Check files and directories permission and ownership.

4. Check that your website is not triggering any mod security rules.

5. Please check the the issue with theme and plugin provider.

6. Check your website is not exceeding resource limit/inode limit allocated to it.

7. If all above is fine then please remount the "cagefs" - 
cagefsctl --remount-all

It fixed my issue!
