XF 1.4 External Accounts - Issue with all


My users can't seem to integrate Facebook, Twitter, or G+ via the 'External Accounts' link in XenForo. They get the following errors:

For FB: App Not Setup: This app is still in development mode, and you don't have access to it. Switch to a registered test user or ask an app admin for permissions.

For Twitter: An unexpected error occurred. Please try again later.

For Google: 401. That’s an error. Error: invalid_client no application name

I'm sure I must not have something set up correctly - but what?
ok, but I had gone through those directions once before. All the APIs and Auths are already in there for the integrations.

For example.. Google. I already have the Client ID and the Secret filled in. It should be ready to go and working. Same with Twitter and FB.
