hi, all. our librarian changed something (she does not know what) in the global preferences for circulation, and now we can't access any of the circulation preferences (all other preferences appear fine). when you select "circulation" in the preference list, the following error message appears. any idea what we need to do to repair this (or what is wrong)? any help is greatly appreciated! thanks in advance.
