thanks,
I have 2 question:
1. is there different between 5 star rating with 10 star rating for google system? I want to know if I use 10 star rating may hve problem with google rich snippets?

2. can you help me about Google Rich Snippets option in plugin panel?
my WP is RTL system and so the place of radio button of “Yes” and “No” changed in plugin option page,so I cannot realize correctly Yes or No,so I check the wp options table in phpmyadmin database and checked the row “postratings_options” , it show this comment:
—————————–
a:1:{s:11:”richsnippet”;i:1;}
—————————–
can you say me with this rule,my Google Rich Snippets is Yes or No?

I test my site and a post of my site and the result was “All Good” too.

1. I don’t know
2. Yes the Rich snippet is enabled.

If your test your site and everything is good, wait for Google to crawl it again.

ok thanks,
I doubt maybe the 10 star don’t allow to show star in google result,how can I found what is the google rule for this situation?
