When the website is accessed with disabled cookies (or a cookies whitelist), the message "Dein Browser wird nicht unterstützt oder Javascript ist deaktiviert" is shown. However in my case the browser (recent Firefox) is supported and has JavaScript enabled - just the cookies are in general disabled, using a whitelist. So that error message should also mention cookies as reason.
