Thanks for the reply. Just to be sure before I order:
1. When you say to backup, you mean to backup all the plugin directory of the wp review plugin via FTP Or do I need to backup something else that is not found in the plugin directory?
2. I need to unistall the previous version via my wordpress dahbaord and then install the new one, correct? This way everything should be fine with the reviews that are already on my site?
3. You didn't answer my question about the rich snippet stars. Does everything work fine with them in this current version when it comes to the google search results page? If I will install the new version of the plugin, my current reviews will show the stars in the search results now without any further action (after google will crawl these pages again)?
Please let me know
Thanks
