Stars not displaying

I had an issue with the rating stars not displaying on reviews or form. (when logged into wp-admin the stars displayed ok- log out..gone)

I discovered when the page rendered the css was looking for the newstars.png in this location:

http://fonts.googleapis.com//newstars.png

this may be because of W3TC caching not sure

Here’s what fixed it edit the plugin css file:
wp-customer-reviews.css

replace newstars.png with absolute address:
http://www.example.com/wp-content/plugins/wp-customer-reviews/newstars.png

Hope this helps someone and maybe a fix can be incorporated in future release
