I just used the auto-update option to apply 2.02. All line charts are now showing as dark gray lines on black background. Column charts appear as red bars on white background as expected. Tested using different browsers (latest firefox and chromium on ubuntu, all with the latest updates to browser plugins) and the black charts appear on either.
What do I need to do to correct this? All visitor tracking appears to be working correctly.
(I’ve already tried deleting all contents of /tmp directory to no avail.)
