File upload via Diagnostics|Command prompt|Upload doesn't work.
I have double checked this and compared to a 1.2.3-R that I have running.
In 2.0.1 when selecting and then pressing 'upload' of a file no message is shown on top and the file isn't found in the system either. Not in /tmp and not anywhere else either.
In 1.2.3-R this works very well, message is prompted back on top of page that the particular file was uploaded to /tmp and it's easy to verify, by using ls in the command window on the same page for example, that this is the case.
Since this is a very handy feature and since it used to work it's infortunate that it stopped doing so.
