Mine says this NOW:”URL Blocked: This redirect failed because the redirect URI is not whitelisted in the app’s Client OAuth Settings. Make sure Client and Web OAuth Login are on and add all your app domains as Valid OAuth Redirect URIs”…but before it used to say same as you “Something went wrong”..and my post to pages option is greyed unavaiable and the post url from a Facebook merchant or event then I get {error: something wrong 190}…used to work but I only had time to place 2 entries into my directory while learning all this stuff….
