your demo doesn't work

Same here, selecting goes well, but does not send invite!

However neither does the example on dev facebook, so the problem might be Fb itself https://developers.facebook.com/docs/reference/dialogs/requests/

The plugin is broken due to a Facebook API change

Could the developer just let us know if he’s going to update it or not? It’s a very nice plugin and i’d really like to see it in action.

Where are you Author? I need you ?? It don’t work, my friend not receive my invition.

nobody receives invitation.

Im working on new plugin. Its called WordPress Authors Inviter
