After installing JoomSEF the rating buttons, thumbsup and -down, have ceased to work. No voting is registered and after pressing the buttons it takes only a few seconds before being redirected to the front page. Not sure why it is redirecting to the frontpage, and it is annoying to our customers.

No errors are showing and no 404 is shown (even though I have opted to have them shown in JoomSEFs config).

What is going on and can this be fixed? If not I see no reason for using $10 on the Quickfaq extension.
