If the bars are appearing as error messages, probably you do not have GD installed. If they are appearing as grey boxes, or broken images, you may have GD installed but with the wrong image support. Older versions of GD only make gif images, newer ones only make png images. You can set PNG=0 (to try GIFs) or PNG=1 (to try PNGs) in the routers2.conf file.
Finally, if you are on UNIX, it is possible that you have an older libgd.so but a new GD.pm, which will make neither work. In this case, upgrade your libgd, and then reinstall GD.pm.Statistics: Posted by stevesh — Wed Feb 08, 2006 1:02 pm
