Pluhnews Problem - Help Please!

[weallgoboing]

My install of vBulletin is in http://weallgoboing.com/forums/

and I run Pluhnews successfully in http://weallgoboing.com/forums/newsnow.php

I am trying to make Pluhnews run in the root, eg http://weallgoboing.com/newsnow.php

I have adjusted

require("global.php");
require("PluhConfig.php");
require("admin/config.php");

to

require("forums/global.php");
require("forums/PluhConfig.php");
require("forums/admin/config.php");

but get a blank screen, no error messages and no headers!

Any ideas?

(p.s. http://weallgoboing.com and http://weallgoboing.com/forums/newsnow.php exist, the other url's are examples but not live.)
