I just sent out a mass mail to the 10k or so ModMySite.Com users with the advanced_settings.php and turn off "BoonEx News In Admin" fix stuff.... the same problem & solution as a while back when BoonEx had a problem and people could not get in to their admins. We sent out a mass mailing then too.
Anyways, should cut down on the panic some (at least for the people in our database).
