Can't update Facebook release

I’ve updated the Q&A and want to release a new version but it’s not working. See screenshots.


Have you tried to click “Continue with Facebook” to release a new one?

If you have not released for a long time, or there’s no one using it, or any other reasons, Facebook may have expired the access token. You need to release again to renew the token. “Update” won’t do, as the error message clearly says.

Yes I have tried to release a new one, that’s when I get the " Invalid anti-forgery token" error message and am unable to proceed.
