Not a bug  Facebook Intergration.

Your account is not currently associated with a Facebook account.

Associating with Facebook makes it easier to share interesting things with your friends and import content from Facebook here.

I push the button and get
"error": {
"type": "OAuthException",
"message": "Error validating application."
And i get the same thing in the ACP

This is a Facebook generated error, so it's not something we can control. It's likely from incorrect details being entered into the FB integration options in the admin CP. In this case, probably the secret.
