The solution is very simple, open PHP.ini, set the display error

display_errors = On

Then open IIS and restart FastCGI.

HTTP 500 Server internal error. The reason for this problem is that statements such as require(./xxx.php) are used in the index.php files of programs such as phpmyadmin and wordpress. It is usually a file or database permission issue.
