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,

waterfall.inc file of 322 lines of code are as follows:

for ($ms = $interval; $ms < $max_ms; $ms += $interval) {
$x = $x_scaler($ms);
imageline($im, $x, 1 + $row_height,
$x, $data_height - $row_height, $time_scale_color);

I tracking code and found $x is null, caused the code did't continue to perform, as a result, $im is blank. but i can't understand all of the code, so...
