I have a similar problem, which I just now found time to get back to
looking into. upsstats.cgi produces a basically correct-looking page,
except that everywhere there apparently should be retrieved data, there
is instead "[error: Invalid argument]". I did the necessary webserver
configuration to be able to call upsimage.cgi directly, and it returns a
HTTP content-type: header followed by a PNG image containing, in yellow
text on a white background rendered vertically from bottom to top (i.e.
rotated 90 degrees counterclockwise) the following message:
"No host or display"
Unfortunately I can't at this moment tell you how nut was configured,
because I lost the configured source directory in a three-disk cascade
failure that took down my disk array. I'll have to re-download and
start configuration over from scratch.
