my readers don’t “see“ the stars option

Hello all
I installed the Yet Another Stars Rating to my website (o365info.com), So, my reader will be able to rate my blog posts
I have configured the following settings
Auto insert options Visitor ==> Votes
Use only in custom post types ==> No
Where ==> Before the post
Rich snippet options ==> Aggregate Rating
The problem that I cannot see any “stars” in my post only the [Total: 0 Average: 0]
In other words, my readers don’t “see“ the Visitor Votes (stars option )
Any idea?
