[ic] Error when saving in Admin Interface

[Brendan Crosser-McGay]

Has anyone else experienced the problem of having an internal server error
500 when they use the Admin interface Save button, or when using other
features of the Admin Interface, I seem to get this message in my error log,
and I under this error looks pretty simple but I don't know where the
setting is that is making it do this:

/cgi-bin/2002/admin/page_edit search error: your search file a valid
database reference, was 'backup'

I imagine theres a default setting that needs to be changed somewhere, but I
can't for the life of me find it..  If someone can help thanks!
