Every time I request a .php file I get the 500 error code.

I tried many different file permissions and searched the whole internet (or at least, it felt like this), but i couldn’t find anything helpful. (It’s not an easy to find suexec error or something like that. However I guess, it’s something with the permissions… and probably I just don’t know a/the certain point…)

Quite long… I hope, this isn’t too much 😉

Please don’t mind wrong language, if something is wrong.
And yes, you should be able, to access the server: http://wiheha.us.to/

    I (accidently) found the solution:
    The fcgi script (and the directory containing it) has to be at least publicly executable (r-x–x–x / 511).

    updated file structure:

    drwxr-xr-x root   root    /var/
drwxr-xr-x root   root      www/
dr-xr-xr-x wiheha wiheha      wiheha/
dr-x--x--x wiheha wiheha        conf.d/
-r-x--x--x wiheha wiheha          php.fcgi
drwxr-xr-x wiheha wiheha        www/
-rw-r--r-- wiheha wiheha          favicon.ico
-rw-r--r-- wiheha wiheha          test.html
-rw-r--r-- wiheha wiheha          test.php
