In my Apache console I see the following warning when it is opened:
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
The warning doesn’t seem to have negative effects but I would like to have it repaired.
Now I am using Webmin/Virtualmin and I am wondering whether that could/should be set there.
