Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

I developed a website, using php/mysql running at IIS Server as CGI Server API.

Suddenly it gives me error 500 after two weeks. It has lot of scripts but index.php home is working. But other script that has header redirection

What's wrong with my scripts.

livehttp addon of firefox says..
