HELP! I'm supposed to be giving some users some training tomorrow...I'm using 3.2.2 and I was able to create subfolders when logged on as an Admin or Host, then I ticked to allow a group of users permissions to view and write to folders NOW though when these users logon they dont see anything except the root folder and when I logon as either Admin or Host I can get to the File Manager, but also can't see any subfolders and when I try to create a new one I get the following error in the log file (below). I've search for hours in the forums already to see if anyone has a solution, but can't find anything that has worked...I've synchronised, cleared cache etc.

PLEASE HELP????!!!

Yep that makes sense, however now when I logon as Admin and go to the file manager it still throws me the same error when I try to create any new subfolders.

When I logon as Host, it also does the same thing.

Any other ideas???
Cheers
