I changed my Facebook email address, from
email@example.com (both fictional).
I'm using the Facebook SSO to log in on the SE network. Since I changed my mail address, my Facebook login keeps failing:
Unable to log in with your OpenID provider:
An unexpected error occurred while logging in. It's not you, it's us. This is our fault. Detailed information about this error has automatically been recorded and we have been notified.
I also have Google accounts for both email addresses, and apparently I can log in using my
firstname.lastname@example.org Google account. If I then attempt to add another login, one that is also registered to my
email@example.com address, I get the same error message as before.
