Mamba,
What I did was hide from being seen in the main menu, I did
not deactivate. It is not something I would prefer to have
a user seeing in the menu.
For the record, I did it twice only to confirm the source of
the problem :) I thought it important enough to be able
to report as a problem... wanted to recreate before reporting.
They are development sites and I can recreate them with
a few days of work. Of course I would rather recover them.
I'm using rmcommons 2.1, using the red mexico theme for
admin and mozilli_iso on the site side.
I'll try killing the database entries that refer to it and
change the admin theme, installing the latest version...
