That's the error I get with OpenID now when trying to log-in with a LiveJournal account on my site. I also get this error on DeadJournal now. So do all of my friends using the sites.
Is there something wrong with OpenID all of a sudden? Has something changed? I have not updated any of the OpenID-related files since it was last working. Also, I can log in to LJ with my WR account fine using OpenID.
