I keep getting this warning when I (re)start Apache.

• Restarting web server apache2 apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1 for ServerName

  ... waiting apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1 for ServerName [ OK ]

This is the content of my etc/hosts file:

#127.0.0.1  hpdtp-ubuntu910
#testproject.localhost  localhost.localdomain   localhost
#127.0.1.1  hpdtp-ubuntu910

127.0.0.1   localhost
127.0.0.1   testproject.localhost
127.0.1.1   hpdtp-ubuntu910



# The following lines are desirable for IPv6 capable hosts
::1     localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

This is the content of my /etc/apache2/sites-enabled/000-default file:

<VirtualHost *:80>
  ServerName testproject.localhost
  DocumentRoot "/home/morpheous/work/websites/testproject/web"
  DirectoryIndex index.php
  <Directory "/home/morpheous/work/websites/testproject/web">
    AllowOverride All
    Allow from All
  </Directory>

  Alias /sf /lib/vendor/symfony/symfony-1.3.2/data/web/sf
  <Directory "/lib/vendor/symfony/symfony-1.3.2/data/web/sf">
    AllowOverride All
    Allow from All
  </Directory>
</VirtualHost>

When I go to http://testproject.localhost, I get a blank page

can anyone spot what I am doing wrong?
