Thank for that plugin, it's cool but I've a problem maybe with it.
I use Recipe snipet for my blog and when I check the post with google richsnippet tool, the stars rating not apear, only picture is apear.
Warning: Rating could not be normalized.
Warning: Please provide best and worst.
When some post is rate by anyone, rates are counted.. I have rates, but stars are 0..
Average rating not working for me.
<span itemprop="rating" class="rating-value">0</span>
What to do, or have to waiting some days..?
