We have been using the file upload mod and thought everything was working fine - until recently we have been receiving email from alumni stating that when they try to upload a .jpg or .gif they receive the following error: "unauthorized access".

I thought that we had set this up to allow anyone to upload? We recently added the ext ".JPG" and ".GIF" (uppercase) thinking that maybe it might be a case sensitive problem.

However, it still works for some not others?

Since we are receiving an "unauthorized access" it has to be something with permissions. Does anyone have a clue as to what I should look for to what is causing this problem?

Thanks
