I just noticed an error in the code, which could potentially, depending on your forum version, render this hack unfunctional.
So, in this area of functions.php:
PHP Code:
function checkipban() {
// checkes to see if the current ip address is banned
global $DB_site,$bbuserinfo,$enablebanning,$banip,$webmasteremail,$session,$HTTP_SERVER_VARS,$bbtitle;
Make sure in the
global list that $bbuserinfo exists!
