I have a fix that will hopefully help quite a few people out. I, too, had this very same problem and none of the suggestions above worked. Finally, I noticed that I had a couple of third party WP Upgrade Plug-Ins. I deactivated and deleted them. I went back and tried again and it worked.
IMPORTANT:
I did have to use the localhost as the domain name instead of the ftp site.
Hope this helps a few people.
I have a problem, too, with multi-ratings, though not the same.
My Mult-Ratings Feature is rendered properly on the page or post, but the votes are not saved or tallied:
After submit is clicked it still shows 0:
For example,
http://productreviewratings.com/2009/03/braun-10-cup-coffee-maker-review/
After submitting mult-ratings, Result looks like this:
Rating: 0.0/20 (0 votes cast)
