Is there any new information on this?
Invalid Scopes: user_about_me. This message is only shown to developers. Users of your app will ignore these permissions if present. Please read the documentation for valid permissions at: https://developers.facebook.com/docs/facebook-login/permissions
Not sure if this means that the plugin usage will need to be reviewed and approved by Facebook going forward?
FYI, it is not possible to use the Facebook Social Feed for a new installation at the moment due to policy changes being made after all the bad press Facebook has been getting in recent weeks.
Specifically, enabling the plugin returns this:
(OAuthException - #200) (#200) Access to this data is temporarily disabled for non-active apps or apps that have not recently accessed this data due to changes we are making to the Facebook Platform. https://developers.facebook.com/status/issues/205942813488872/
Thought others may want to know...
