Grateful that I see a reply and even a 'support team' badge. :-) Thanks a lot.
I am afraid this was not the answer I was hoping for....
When I create a menu link to the root cat, I get a blank page, no errors. THe HTML source is completely empty.
Even with the Joomla Debug on I don't get any message.
Caching has been disabled
The only thing I can find is:
Timestamp: 02-11-12 12:36:31
Error: The character encoding of the HTML document was not declared. The document will render with garbled text in some browser configurations if the document contains characters from outside the US-ASCII range. The character encoding of the page must to be declared in the document or in the transfer protocol.

Line: 0
(in the error console of my dev tools)
But that is normal when there is no valid content.
