i’m confused – do you want to restrict the group settings->enable forum option (which restrict group creation plugin can do) or restrict creating a new topic within the group forum? if the later – don’t forget this theme file as well https://trac.buddypress.org/browser/tags/1.2.5.2/bp-themes/bp-default/groups/single/forum.php
