Customized page, root dir.

[Sergio68]

I made this page and it's working at this address http://www.vbulletin.it/forums/prova.php

PHP Code:

<?php

error_reporting(E_ALL & ~E_NOTICE); 
define('NO_REGISTER_GLOBALS', 1); 
define('GET_EDIT_TEMPLATES', true); 
define('THIS_SCRIPT', 'releases'); 
$phrasegroups = array(); 
$specialtemplates = array(); 
$globaltemplates = array(); 
$actiontemplates = array(); 
 require_once('./global.php'); 

        $navbits = array(); 
        $navbits[''] = 'Home Page'; 
        $navbits = construct_navbits($navbits); 
        eval('$navbar = "' . fetch_template('navbar') . '";'); 
        eval('print_output("' . fetch_template('homenew') . '");'); 

?>

If I try to do the same on the root dir http://www.vbulletin.it/prova.php it's not working, can you tell me why ?
