Error Message with Facebook Intergration...

[Cinnamon Bernard]

Hi all,

I've been downloading plenty of apps, mostly games and earning gift card ones. Some of these apps, the login was successful.
Some others, not so much. I encounter an error message when I have to log in to the app via facebook, or even just to sign up.
View attached image:

Can someone explain what the error means, and if there is a way to fix this issue.

Thanks!
