Okay, don't use what I posted before, as I am tired and confused at the moment. Try just sticking this at the beginning of the config file:
Code:
// for use with PHP < 4.1.0 only
$_SERVER = &$HTTP_SERVER_VARS;
$_POST = &$HTTP_POST_VARS;
$_GET = &$HTTP_GET_VARS;
$_COOKIE = &$HTTP_COOKIE_VARS;
$_REQUEST = array_merge($HTTP_COOKIE_VARS, $HTTP_POST_VARS, $HTTP_GET_VARS);
