If I open my remote web in Frontpage 2003 and edit the log, the guestbook
page resets immediately. If that doesn't work, just post a new entry in
your guestbook as a visitor would (say something nice about your website),
and the guestbook will then be updated. Or edit it separately, just like
you did with the guest log page.
I posted a related question an hour before you posted yours, and am still
awaiting some help.
