Suddenly, publishing a post doesn't get it amplified on Facebook. Instead, I get an error message that includes this line: "Error validating access token: The session has been invalidated because the user has changed the password."
Well, I haven't changed the password.
In any case, I disconnect Facebook in my user profile, connect it again (and it authenticates with Facebook), but still this error message.
Only started doing this today.
Any ideas on fixing it? Thanks!
