Has anyone had a problem where the Content Filtering panel in the Web Admin tool quit working?  I have e-smith 5.1.2 with squidguard 3.1.  The Content filter panel was there when I first installed it, but now when I go in it gives me a "Page Not Found" error.  I have re-installed squidguard with no errors, other that the messages telling me that it is already installed.  The filter is functional, I just can't administer it.
Any help would be greatly appreciated.
