ExternalAuth Facebook Login Problem

Hi guys,

I use 3.60 version of NO and my facebook app was 2.2 and everythings works smootly. But on 27.03.2017 facebook plug out Graph API v2.2 and my facebook app version automatly upgrade to 2.3

Now Facebook login options doesnt work. If ı tried to login its return "Unknown Error"

Hi,

The Facebook changed the data format from string to JSON and this is the reason for the error.

There are a few topics in the forum with the same problem that might help you:
