Stars not showing (and ratings disappeared)

Hello,

I’ve been using YASR for a while and it’s been great, but after a recent update all of my ratings have disappeared, and in addition, when I go to add a rating (visitor vote) when logged out or in, all I can see is three black lines, not the empty stars that are usually there for an unrated page.

For example: http://rockandrollfood.co.uk/main-event/mexico-south-america/mains/chili-con-carne/

Do you have any suggestions? I am guessing there is no way of getting my ratings back?
