Perhaps someone will be good enough to help me with this problem.
I have Administration rights over the whole of our Moodle installation. I have setup Course categories and sub-categories for Heads of Department and set them Administration rights at this level. They can create new courses without any problem. However, they are unable to upload resources. If I log on and upload them there is no problem. Once I have uploaded a single file they can upload! It would seem that when they are logged in they are unable to create the initial directory to upload to.
Any help would be greatfully received.
