Yes the status pages display OK. The test command generated an rrd graph.
I've also discovered that most/all of the scripted stuff doesn't work, for
instance when I try to disable a test, the disable screen pops up fine, and
I can select everything correctly, but nothing happens when I hit "Apply".

Thanks,
Larry Barber
