I have been using Gbook for years but after spam attacks I switiched to Ver 1.7
It all seems to work okay until I got a new guestbook entry
I get an email telling me of the entry but the URL to approve it produces a 404 Error, and I have been unable to approve them manually

the url given is
http://www.britishsteam.com/guestbook/g ... prove&do=1

My approvals are now stacking up please help.
