I reverted to the older version of the plugin, but the same problems exist. I have not tested all the review features.
I am running Gpgeo core 1.2.4 and cannot upgrade because we have made some customizations to the core (unrelated to reviews)
In summary I would like to get the following working:
1. stars to show up on ratings (and sub-ratings)
2. reviews to show up in admin and function normally (approve, reject, etc…)
3. Get Rich snippets to show aggregate reviews, and work here: https://developers.google.com/structured-data/testing-tool/
