Never ask "What can be other reasons". We are not weather forecasters here. We are programmers. And have tools to be certain, what particular problem experiencing now.

The only thing you need is to ask PHP to tell you, what's the problem.

The easiest way is to put into your config file these lines

ini_set('display_errors',1);
error_reporting(E_ALL);

and see what your app will say.
It can be permissions or or php.ini. All will be told.
Quite easy, eh? ;)

if these magic lines won't help, there are several other ways, manual has a good manual in it:
http://php.net/manual/en/configuration.changes.php

then your server goes public, don't forget to change these lines to

ini_set('display_errors',0);
ini_set('log_errors',1);
error_reporting(E_ALL);

and see error messages in the error log, not revealing it to the possible hackers and innocent users
