No ideas as such apart from having a look at what your browser says the ’link’ for the vote is doing. My snippet call is:
[!star_rating? &tvName=`MovieStarRating` &onevote=`true` &starTpl=`MovieStarRatingTPL`!]
I guess check that you have the TV created and that its assigned to your desired template and declare it in the snippet parameters (mine is MovieStarRating).
If I hover my mouse over a voting star FIreFox tells me its going to go to:
http://mysite.com/mypage?starvote=3&pid=(docid).
When you click you cast your vote and the page you voted on should re-appear. If
mypage isn’t the same as the page you are on then that could be where the problem lies.
I can’t think of anything else. Sorry. I’ve not had that problem.
