Hi Rolf,
Thank you for contacting Tapatalk!
The forum you are trying to reach does not have a working Tapatalk plugin running, hence causing the issue. We contacted the forum owner to update their plugin. Please report the same to your forum admin as requests from members are looked into more quickly.
