I have checked the uid and gid of www-data, being 33 and amended the fstab permissions as follows:
UUID=537FEF451930795B /media/win ntfs rw,auto,users,exec,nls=utf8,umask=003,gid=33,uid=33 0 0
rebooted the server and still I get the error
You don't have permissions to upload or create files here
Anything else that I can try please.
