Configuration not loaded fron config.php

Under PHP 5.2.3 running as fastcgi, the _drupalvb_fetch_config() function fails to return $config after the first time.

Reason: require_once() will only include 'config.php' one time. I only discoverd this because my vbulletin install is running under a non-default tableprefix.

Quick fix, replace the function with this

//Function to grab the configuration/options of the vB installation
function _drupalvb_fetch_config() {
  global $vbconfig_array;
  if(!isset($vbconfig_array) || empty($vbconfig_array))
  {
     $config = array();
     require_once('config.php');
     $vbconfig_array = $config;
  }

  return $vbconfig_array;
}
