Detailed Navigation is closed by default

Hi,

The Portal with all packages is running fine in test system.

The first Page (welcome) is displaying some KM-News in the content section and has some links in the detailed navigation (DTN).

Then, I exported the ivies/pcd with all roles etc. to the production system.

Now, whatever value I put in "Initial Display" in the roles (Automatic/Open), the first time, the user logs on, the DTN is completely close. If if reload the page, everything is fine and the DTN is open.

I also checked the default framework page, but it is set to "OPEN" as well.

No clue no more.

Thanks for any help
