RE: [help]the waterfall unable to show
Do you see anything in your error logs? If you click on the blank waterfall, does a large version of the waterfall load or is it also blank? Usually you see that problem if gd isn't installed but then the screen shot thumbnail wouldn't have worked either.

Are you using the 2.6 WebPagetest release? PHP 5.3+?

Thanks,
