Windows server 2012 R2, IIS
Moodle 3.3.2
PHP 7.1.11
I successfully set up the Moodle server and everything was working fine. Then the IT team installed few security patches, windows server security updates. Now when I try to load http://localhost/Moodle or http://localhost/Moodle/index.php, A blank page is displayed, Under Inspect Element->debugger tab I found the error "failed to load http://localhost/Moodle".
I tried placing a simple phpinfo file inside Moodle, http://localhost/Moodle/phpinfo.php shows all the phpinfo just fine.
Only the files associated with Moodle show "Internal Server Error 500"/"Failed to load http://localhost/Moodle" error. Please help me fix this.
