I have the last version of this plugin i.e. 1.1.0 an last BP version i.e. 1.7.2. installed on two sites (same WP theme, same BP configuration, same other BP plugins,...) and the behaviour is completely different.
On the first one : works like a charm on frontend / despite no settings - admin page available anywhere on backend.
On the second one : only plugin which screws up the site on front end (blank page) when activated / despite settings available on backend... (including "default group id").
Any hint ? This plugin is SO useful.
Many thanks in advance !
