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.
If you're accessing your site from the server itself you normally get a detailed error message from IIS which might help troubleshoot exactly what went wrong when an Internal Server Error 500 occurs. If not you should be able to configure IIS to provide the detailed error message.
