The recent version of Chrome gives me the "Whooops - Something went wrong, reload the page to start over." message.
The same server & directory works in Firefox. Chrome private mode does not fix it either.
Accessing both via localhost or 127.0.0.1 do not work in chrome, both work in Firefox.

Versions:

• OS: Arch Linux
• chrome: 57.0.2987.110 (64-bit)
• firefox: 52.0 (64-bit)
• node: 6.10.1
• npm: 4.4.1
• ungit: 1.1.11

My server.log (via ungit --logRESTRequests --logGitCommands --logGitOutput)
Chrome's browser console output.
Any other Information I can provide?

by the way: very nice work on ungit!
