You don't have permissions to upload or create files here - local (external ntfs-3g storage)

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.
