Running DNN 9.3.2, I have installed and configured DotNetNuke Facebook Authentication Project 

as well as followed the instructions here for setting up Facebook. https://www.dnnsoftware.com/wiki/conf...

My Login Screen is pointing to this strange URL for some reason: http://santiagoperezart.com/Home/tabid/92/ctl/Login/language/en-US/Default.aspx?returnurl=%2fen-us%2fhome.aspx

I'm getting the following error message after I click on the "Login with Facebook" button on my login screen.  

{
   "error": {
      "message": "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 subdomains of your app to the App Domains field in your app settings.",
      "type": "OAuthException",
      "code": 191,
      "fbtrace_id": "AmzDgzOPyyI"
   }
}

When I look at the App Basic settings in Facebook I can clearly see my domain is listed: 

What am I doing wrong? What domain is it looking for on click? 

Santiago,

there is... but I must say that I don't know too much about the Facebook provider, and propably some of the other colleagues as well. Sorry...

Happy DNNing!
Michael

AFAIK this is an issue that has not been reseolved yet: 
https://github.com/dnnsoftware/Dnn.Pl...
My advice would be to add your findings there. 

Slightly off topic: we are currently also working on a auth0 provider that would allow you to connnect social media. But that will take some more time.
