RE: Waterfall Not Showing
Thanks Andy! I enabled GD and the images are showing now. However, the waterfall is not displaying all page objects. My private instance is showing only base html whereas http://www.webpagetest.org displays more than 20 page objects. See attached. Is it a config issue or something else?

RE: Waterfall Not Showing
Make sure you are using the latest agents: https://sites.google.com/a/webpagetest.o...est-Agents

It's possible that a bug was fixed after the initial release. Otherwise you will need to enable tcpdump and video capture and just compare both to make sure they are actually getting the same page.
