Facebook authentication error in NOPCommerce - since Facebook enforced the Can't load URL: The domain of this URL isn't included in the app's domains. To be able to load this URL, add all domains and sub-domains of your app to the App Domains field in your app settings.

NOPCommerce needs a slightly different redirect to other apps - the Facebook login feature is a plug-in in the plug-ins folder and so the actual redirect page should be:

https://storedomain.suffix/plugins/externalauthFacebook/logincallback/ 

https://developers.facebook.com/apps/ Application#/fb-login/settings/

As per:



You should not need to change the domains under settings.
