Please post the code in your PHP file, and maybe we can determine the issue.
I was actually hoping for a little help figuring it out. This is what I got. I may have something wrong, but I think I did what the instructions said.
PHP Code:
<?php
// ####################### SET PHP ENVIRONMENT ###########################
error_reporting(E_ALL & ~E_NOTICE);
// #################### DEFINE IMPORTANT CONSTANTS #######################
define('THIS_SCRIPT', 'about');
define('CSRF_PROTECTION', true);
// 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('about',
);
// pre-cache templates used by specific actions
$actiontemplates = array();
// ######################### REQUIRE BACK-END ############################
// if your page is outside of your normal vb forums directory, you should change directories by uncommenting the next line
// chdir ('/path/to/your/forums');
require_once('./global.php');
// #######################################################################
// ######################## START MAIN SCRIPT ############################
// #######################################################################
