I disabled ajax features and got the same error:
"admin, you do not have permission to access this page. This could be due to one of several reasons:

Your user account may not have sufficient privileges to access this page. Are you trying to edit someone else's post, access administrative features or some other privileged system?
If you are trying to post, the administrator may have disabled your account, or it may be awaiting activation."

Described box is for sum of thumbs up for first post. Of course You can do this box for others options like counting every thumbs in topic or displaying sum of thumbs up and sum of thumbs down.
