I have a question.
I have installed plugin and used Item Review option for some of my posts.
That was maybe 3 weeks ago. When I test links on http://www.google.com/webmasters/tools/richsnippets it shows rating. But in google search it shows without rating.
In webmasters tool I also get:
name: my product name
offers: Item 1
description: my product description
Error: Incomplete microdata with schema.org.
Can this error be a problem why it is not showing rating?
