Localhost does not work

[dobyabywal]

Apache and MySQL both running. Had to change Apache listen from 80 to 78.
Running Windows 8.1. Browser is Firefox or Chrome. When I type in localhost or 127.0.0.1 or http://local host I get "This Web Page not available [in Chrome]," and "Y=Unable to Connect[in Firefox]."

[FGA] Changing the Apache default ports

[dobyabywal]

When I originally wrote around 8/15/2015 I had changed the Apache "listening" port from 80 to 78 because I got a message that 80 was not available. Apache worked on port 78, but I wanted to see what app was blocking port 80. In the windows Command Prompt I typed: netstat -ano |find /i "listening". I could see Apache on port 78 and MySQL on 3306, but nothing on port 80. Today, 8/21/2015 following your suggestion to keep Apache listening to port 80 I changed it back and now it works. I sure would like to know why why it was blocked days earlier and not now.
