Broken styling in externally powered vbulletin page

[SwalyAaron]

This is how my code looks like

<?php
chdir('/home/sitenamehere/public_html/forums'); 
// ####################### SET PHP ENVIRONMENT ###########################
error_reporting(E_ALL & ~E_NOTICE);

// #################### DEFINE IMPORTANT CONSTANTS #######################
define('NO_REGISTER_GLOBALS', 1);
define('THIS_SCRIPT', 'test'); // change this depending on your filename

// ################### PRE-CACHE TEMPLATES AND DATA ######################
// get special phrase groups
$phrasegroups = array(

);

// get special data templates from the datastore
$specialtemplates = array(
    
);

// pre-cache templates used by all actions
$globaltemplates = array(
    'TEST',
);

// pre-cache templates used by specific actions
$actiontemplates = array(

);

// ######################### REQUIRE BACK-END ############################
require_once('./global.php');

// #######################################################################
// ######################## START MAIN SCRIPT ############################
// #######################################################################



....the rest of the code is fine

My problem is that styling is messed up, non of the CSS is showing
