Still strange behaviour. When logged in as user/admin in wordpress I can rate the items in the table only once. If I rated an item as admin and come back as a guest, I can’t rate again (good). If I did not rate as admin and come as guest I can rate over and over again. When I log in as admin I can’t rate.
So there must be something different about the Unique IP code. It works when logged into wordpress. It doesn’t when I’not logged in and the item has not been rated…
