Maybe you do have the config file right, but you browser might cache the
resulting graphics. Furthermore the week, month and year doesn't get made
every time you run the script. 

Solution. Remove all png/gif files from the workdir in order to get mrtg
to make all graphics again. Run mrtg in the hand to check that there is
no errors. If you use netscape (you probably do on HP-UX or SUN :) press
the shift button and press the reload button with the mouse, to reload
