I've successfully installed the plugin, set it up and authenticated with Facebook in the WordPress control panel as per the instructions at https://developers.facebook.com/wordpress/#author-og-setup. My app is located at https://developers.facebook.com/apps/435659916466791.
I've then published a post, which appeared successfully in my Page's Timeline. When I go back to the Open Graph tab in my app settings and click on 'submit' next to the new publish action I get an error that reads "Publish Actions: You must publish at least one action to your Timeline using this action type."
I am really not sure what to do to resolve this issue? I have published more than one action, yet it's not being recognized. Any suggestions? Is it possible one (or more) of the settings in my app are incorrect?
