I keep getting this random error on my home page. Does anyone know what the cause of this could be?

CGI Error
The specified CGI application misbehaved by not returning a complete set of HTTP headers.

Report your OS, server, PHP version information, so anybody could tell you more.

So far I could tell that it is internal IIS server configuration error. You have IIS server, and nobody could give any warranty that PHP executes on IIS normally. However - when exactly this error appears, when you are trying to do - what operation?

Also, try to uncomment $metaLocation='go'; setting and see what happens...

thanks for the input... I'm sad that PHP is unstable on IIS because I'm a Microsoft Professional and it's basically all I know =( . I tried the metalocation trick and I didn't get any change. I am having problems with another piece of software called agilebill written in PHP so I can see how this is a server error and not a software error ( especially since your software is tried and true ).

Additionally - PHP compiled as CGI module works not really well, specially on IIS.
