domains down after phpmyadmin install attempt

Hi

Bit of a newbie and trying to learn command line/linux fast for my Ubuntu 10.04 LTS

Had my site running perfectly then decided it would be a great idea to install phpmyadmin from instructions at https://help.ubuntu.com/community/phpMyAdmin. Did the following:

1. sudo apt-get install phpmyadmin

2. Then went to http://MYIPADDRESS/phpmyadmin and received and 'Unable to connect' page on Firefox.

3. Worried so added Include /etc/phpmyadmin/apache.conf to /etc/apache2/apache2.conf and I still have no luck and am in a bit of a panick!

Now getting the following on log:

apache2: aprsockaddrinfo_get() failed for cerebraluk

apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName

PS Sorted PHP Deprecated: Comments starting with '#' are deprecated issue so I think this is unrelated.

If anyone can advise it would much, much appreciated. I'm having a right sweat over this as it's alive survey based site!

PPS Would love to go back to the start even if it means not having phpmyadmin so if there's an easy way please advise :-)

PPPS Not even sure now what apache.conf should even look like for a normal setup?

Thank you
