Facebook login is currently unavailable
I'm setting up a 'Login with Facebook' button and have it on a test page. http://www.digitalinkmultimedia.com/my-account
I believe I have things set up correctly for the app at developers.facebook.com. The app says it's public and available. I'm using Business Catalyst as the CRM, and the facebook integration appears to be correct (App ID, App Secret, etc)
When I click the login with facebook button the first time I get the message about my profile info being shared....but when I continue I get a 'Facebook login is currently unavailable'.
One thing I noticed is that when the popup first loads the FBTOKEN parameter has a number in it, then it quickly changes to FBUTOKEN=00000000-0000-0000-0000-000000000000#=
Any suggestions would be appreciated.

If you're experiencing this now (end of 2020) it might be due to a pending "Data Checkup":
As part of an ongoing effort to protect user data and drive long-term value for developers, Facebook has introduced an annual Data Use Checkup for app admins to certify that their API access and data use comply with Facebook Platform Terms and Developer Policies, together with all other applicable terms and policies.
Enter https://developers.facebook.com/apps and you should see your app in red color with a note that Data Checkup is due.
You'll need to spend a few minutes to fill in a simple form...
After you're done you should be good 👍🏼
