I've been trying to figure this out for some time
I am using gd-star version 1.9.22
The stars are showing up fine on my posts and people can vote on it
I checked with google richsnippets and it is registering the stars correctly.
However, google is not picking up the rich snippet in the SERPS. When i type in chache:www.xforextrade.com/optionbit the stars don't show up and it just says: GD Star Rating a WordPress rating system.
I am using W3 Total Cache plugin as well.
