Detailed navigation not shown
we've a problem with our detailed navigation in the portal, EP 6.0.
Last week a user told me that he can't see the detailed navigation anymore.
And today another one.
All other users (about 400) are able to see the detailed navigation.
We didnt't import a new SP or anything else. Deleting the cookies of the user or clearing the navigation cache in the portal doesn't work. If the user calls the portal on the client of a collegue, it won't work neither. We've an own Frameworkpage, but this has been running for 2 years and the DTN in the Framework is marked as shown.
Does anyone knows what happend?
