I would like to try your plugin, but can't even get it activated. The following message was shown when I tried it:
Fatal error: Call to undefined function add_review_option() in [correct but anonymous path]/wp-content/plugins/all-in-one-schemaorg-rich-snippets/index.php on line 127
Nog being a programmer, I can't really figure it out. I see that the function exists in settings.php, but somehow it doesn't work.
Thanks for your help!
