Well, I used the "Quick Permissions" feature to assign open editing to anonymous for one wiki page only, and after doing so, my entire wiki is open to anonymous editing, everything. It's in a dangerous state right now unless I completely take it off line. And this action cannot be undone per the warning, which I was ok with as long as it was just that one wiki page, or single object. So now I have a wiki that is completely open to anonymous editing, and I cannot undo it.
Any help is greatly appreciated.
