How do I kill a session in Opera?

I am writing these lines with my previous browser (Firefox), because I am locked out of Opera Forums when I use Opera!

I reset the password to my account, and then I got the error message "Sitzungsdiskrepanz. Es scheint als wäre deine Login-Sitzung nicht mehr aktiv oder sie passt nicht mehr mit der des Servers. Bitte aktualisiere diese Seite.."

In English: Session discrepancy. It seems like your login sesion is no longer active or does no longer match that of the server. Please reload this page".

And no matter how often I reload the page, the error keeps coming back. Even shutting down Opera, restarting and reloading the page does not help. Even killing Opera and rebooting does not help,I also created a new account (because auth.opera.com still works), but even within the freshly created account I get the same error message!

There is no "logout" option... I can not log out of Opera Forums and log back in, so I need a sure way to kill the session data that Opera keeps...

Thanks

(will cross-post this to general, because It is also a shortcoming of Opera Forum software)
