Review star not showing.

Hi,

I am immensely in love with the plugin by the way. I have this small issue here. If you visit the link that I have attached, and look at the review section of the product, initially each review has its star-rating being shown to left of the reviewer name. Now if you select most recent filter on the review, the star-ratings for the review is not being loaded. Also it happens when you search for a review and that the reviews in the search results don’t have star-ratings loaded.
I don’t know why it is not loading the star-ratings. It used to work just fine a couple of days ago. I tried to disable other plugins but didn’t work.

I would love to hear from you guys what might be going wrong here.

Thanks and regards!
