I had multiple virtual hosts and everything was working perfectly, I added an extra one today and now all my previous hosts redirect to the new one.

This is what I get when I run apache2ctl -S

AH00558: apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1. Set the 'ServerName' directive globally to suppress this message

Any idea what’s going on and how I can fix it?
