PHP Page for Real Chat Integrate

[Jaime82]

I have RealChat Integrated with Vbulletin using this PHP page. It works great with one exception, when I don't make a new window open when the user clicks the "Login" button after entering their username and password it comes up with an error saying "Internet Explorer has stopped working" and then it closes the browser. Can anyone tell me what the error is in the code that would make it close the browser, unless I make it open in a new window?

Thanks in Advance!

Jaime

PHP Code:

<?php
error_reporting(E_ALL & ~E_NOTICE); 
define('NO_REGISTER_GLOBALS', 1);
chdir('/var/www/vhosts/url.com/httpdocs/bbs');
include('/var/www/vhosts/url.com/httpdocs/bbs/global.php');
chdir('/var/www/vhosts/url.com/httpdocs');

if (!in_array($vbulletin->userinfo['usergroupid'], array(5,6,7,9,14))){
