“This doesnt work main page goest blank.”

What doesn’t work? Which version did you try to use?

A PHP output turning completely blank often means that an error occurred but you have error display turned off. This makes it very hard to debug your problem. You can turn on error display by including something like this at the top of your site:

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