Icinga and fcgi

[maxxer]

Hi.
I've installed Icinga on a debian server follwing this wiki:
http://www.howtoforge.com/server-mon...n-ubuntu-11.10

The problem is that I use php with FCGIWrapper, thus when I try to access the Icinga web I get a lot of internal server error, because the php script cannot access Icinga web files.
Is it possible to fix that?
Should I add a web user for icinga files? Or is there another solution?
thanks
