Hello,

I am trying to integrate Facebook login on my website. It is still in testing mode and using a sub-domain URL too. It will use the correct domain name once we go live. I am using DNN Facebook authentication provider for this. I created an App on facebook and got the App ID and the secret key. But my facebook login is not working and getting an error. Why is this? I copied the Log viewer for this. Please, can you advise me to use this? (I edited with ***** for the website address.)

And is there any instructions or reference link to find how to set this Facebook authentication provider up with DNN login properly?
