Seems like stumbled on one of those -  if (!-f $request_filename) { ... 
doesnt take in note index directive files...

Eg if you open http://domain.com  instead of the index.php the if() is hit 
and in my case 404 returned :(

Is this also expected that $request_filename doesnt containt the index file 
if there is such in config and also on disk?
