in admin, includes/oauth/adapters/facebook/client.php, there are two calls to the Facebook API /me/groups. In the first, you properly call it as such:
parent::api('/me/groups', 'GET', array('access_token' => $this->token, 'limit' => 500));
In the second, however, you do not specify the limit. Thus, Facebook's limit of 25 is imposed, and this is insufficient for anyone with more than 25 groups in their Facebook account. Can you please add the limit of 500 to the second call? 500 seems a high enough number. 25 isn't even close
Thank you!
