Blank Screen after Signup

I have installed vshare on my VPS. But after the installation, when I try to signup as a new user, I get a blank screen after clicking the submit button. First I thought its .htaccess problem but even after replacing the .htaccess, i am getting the same problem.

Please Help.

add following lines into include/config.php

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


and try signup
