I think they disabled container, use, and some other permissions. If you changed these settings before the turned them off you will not be able to fix it with admin assist, I think.
<6/25/12> I just removed my old res and put up a new one. It turns out that [-container or container false is the default] and with the permissions to change this "off" all of my chest are locked for everyone but me. My allies cannot access my chest. Is this the intent? I did /res default to make sure I was at the default settings.
Another thing is that pvp is off in default as well, which I don't mind but I didn't think we would want this on this server.
All the other defaults seem right.
