Yes, both recursive and non recursive. Refreshed, cleared cache, restartet application, restartet IIS, checked and reset IIS etc..

None what so ever. All standard folders from the system except one folder I created called "Upload".

Anyhow, it worked before I upgraded.

Anybody got a clue on this?

I found some identical id's in the xml files for the smiley gallery but that only solved some of the errors I got.

Here is what the filemanager throws :

FYI I replaced portalname and url in the log here.

I reinstalled forum, gallery, updated all modules, updated latest .net 2.0 components etc. Still the same error where the filemanager can only see the first 3 folders and my users can't upload to the forum because the forum can also just see the first 3 folders to which the users does not have access.

Help would be greatly apreciated.
