[BUG] solved

users that have their root directory "/" instead of "/forums" and are unable to use the links due to the mod putting in /forums (eg: xxx.com/forums/config.php..instead of xxx.com/config.php)...go to config.php and change

$ibforums->vars['base_url'] = $forumpath . "/" . "arcade.php?".$sess."&";
$ibforums->base_url = $forumpath . "/" . "arcade.php?".$sess."&";

to

$ibforums->vars['base_url'] = "arcade.php?".$sess."&";
$ibforums->base_url = "arcade.php?".$sess."&";

voila...problem solved
