@hallsy @akukskuks Normally, the “Create Group” and “Create Blog” (for multisite) buttons show up beside the Group/Blog Directory Title. The buttons do not show up if the_title(); tag in your theme’s page.php was placed outside of the WordPress loop.
There are different ways to address this issue. One way is to create the link for logged in users. For example, your WP/BP is installed in domain root, http://example.com, then the link t create a group would be http://example.com/groups/create/ by default.
