Breaks multi-user site

I installed the Changetip plugin and configured it for one user, but as a result, any other user without admin priviledges was greeted with a “You are not allowed to do this” message when trying to login. I don’t see why that should happen, but i was faced with either upgrading other writers to admins (which I grudgingly did for a couple of hours) in order for them to continue writing their posts, deleted ChangeTip. That’s right, for some reason, even disabling the plugin wouldn’t let non admins login, it had to be deleted from the installation…

So. 1 star for me. I’d be interested in looking at it if it gets fixed, though.
