In Google Chrome (on my Mac) the lower (black) part of the page is missing. In FireFox I can see it just fine.
It works for me. Try Shift+Command+R to force reload?
not for me...
Version 56.0.2924.87 (64-bit) Google Chrome is up to date.
You need to give more information if you want me to do anything about it. Please read the Bug reporting best practices page. Try on different machines. Try from a private browsing session. Try clearing your cache. Try from a VPN to somewhere else. Send a screenshot so we can see what you are actually seeing. Etc.
Thanks! "Clear Browsing Data" did in fact solve it!
