I am getting this issue as well after upgrading to 2.2.3. I’m still running WP 3.4.2 but about to upgrade to 3.5.

Just to re-iterate, Private Forums are not showing but returning the following error message with DEBUG on: “Notice: Undefined index” and my custom 404 page is returned.

I’ve tried logging in as admin, then out again, deleting cookies and refreshing the Permalinks.

Hope someone can help, thanks.
