http://localhost/ not working

Solution 1:

Check that you have this line in /etc/hosts:

127.0.0.1       localhost

If it is not there, add it.

Solution 2:

if you are using firefox, Uncheck

File > Work Offline and then try again.

Solution 3:

Chrome doesn't like localhost. Try http://0.0.0.0/

Solution 4:

Update: The newest versions of Google Chrome have fixed this issue. It should be working now.

It sounds like you're using Google Chrome or Chromium - This is a bug in Chrome that I've been meaning to report (but never got around to it). Google Chrome attempts to automatically detect a "Working Offline" status and will not allow the user to easily change it

Unfortunately with Chrome right now, you must be connected to some form of network to use localhost.
