The SocialAuth version used by MonoX is 2.1, but the latest is 2.4: https://www.nuget.org/packages/SocialAuth.NET
Is it possible that you just need to update the version of SocialAuth used?    
Alternatively, you can specify an older version of the Facebook API, as the AdditionalScopes scopes in MonoX web.config are invalid in the current Facebook API.

Is it possible that you just need to update it?  I can't do it myself because I don't have the MonoX source, and log4net is a common dependency with a public key token change.

Can you check in your Facebook app settings which version of the API you are using and let us know? Also which version of MonoX are you using as the latest MonoX is using 2.4 version?

Regards,
Mario

Hi,

I downloaded MonoX from this website two days ago: "MonoX Portal Engine v5.1.40.5152 created on 7/6/2015"
Using Facebook API 2.5 - I created this Facebook app last month.

Hi,

We are working on it. There seem to have been changes in FB API and SocialAuth.net doesn't seem to have been updated to handle the latest API changes. We will let you know when a fix is available for this.

Regards,
Mario

Hi David,

Please could you replace your current SocialAuth-net.dll with the attached one. We have implemented needed changes due to changes in the FacebookAPI v2.4+. It should work, however if you find any issues please get back to us.

Regards,
Darjan

I've seen similar issue with http://trafilm.net (have removed social login for now there) that is under development.

I had cloned that from http://social.clipflair.net where social login still works fine

is it that newer facebook apps I create use the newer facebook API and olders use previous one? Can I choose FB API version somewhere at my app settings on Facebook dev site to tell it to user older API? Or should I just try to use the newer DLL? Note that I use MonoX v4.9.40.4845 [12/25/2013], DB v4.7.3842

Tried to use that DLL and get internal server error, guess it's for newer MonoX only. How can one get a fixed one for older MonoX?

Hi Zoomicon,

New Facebook apps can use only newer Facebook API versions and older can use older API versions.
You can check which is the oldest Facebook API version for your app in app dashboard: https://developers.facebook.com

Can you please paste error messages from log here ?

Best regards,
Slaven
