title: php5 with mod_fcgid results in 500 error - probably wrong permissions
body: <p>Every time I request a .php file I get the 500 error code.  </p>
  
  <p>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...)</p>
