Your hostname could not be resolved to an IP
address. This means that /etc/hosts is not set up correctly, and/or
may be there is no dns entry for your Domain. Please be sure that
the contents of /etc/hosts are configured correctly, and also that
there is a correct 'A' entry for the domain in the zone file.
Some or all of these problems can be caused by /etc/resolv.conf
being setup incorrectly. Please check that file if you believe
everything else is correct.
You may be able to automatically correct this problem by using the
'Add an A entry for your hostname' option under 'Dns Functions' in
your Web Host Manager.
