I am getting the same error. On my server I tracked down the problem 2 files; one named #hidden and the other named #root. I can upload the files, but the server will not allow access to directories and files created in either of the files (#hidden or #root). Seems the server does not like the use of the pound sign ( # ) in a filename.
