This is your path to your site
Code:
http://members.lycos.nl/inferion/mohaa/
Right?
That should be set in your PHP-Nuke Admin/Perferences and in your Forum Admin/Configuration.
I notice you have some broken images that are looking to
Code:
http://members.lycos.nl/images/topics/phpnuke.gif
Check those settings...
I doubt that is the root of the problem, but need to make sure those are set right.
