What version of PHP are you running? If your PHP is less than version 4.1.0, add the following to the top of the config file:
Code:
if (PHP_VERSION < '4.1.0') {
$_GET = &$HTTP_GET_VARS;
$_POST = &$HTTP_POST_VARS;
$_COOKIE = &$HTTP_COOKIE_VARS;
$_SERVER = &$HTTP_SERVER_VARS;
$_ENV = &$HTTP_ENV_VARS;
$_FILES = &$HTTP_POST_FILES;
$_REQUEST = array_merge($_GET,$_POST,$_COOKIE);
}
