Nevermind! Issue solved:
Groups_User_Group::delete($user_id, $group_id);
Doesn’t accept an array I guess.
I posted a reply in the gvectors.com forum about this, but also wanted to chime in here too. This is definitely broken. Version 4.1.4 does not exhibit this issue and it seems to have popped up in version 5.
Sorry to be annoying, but since the bug was not acknowledged in either forum, I wanted to make sure this got some attention. This is a great plugin, but unfortunately this is a bit of a show stopper.
