  <p>I've tried changing the ports.conf to Listen 80 and Listen 0.0.0.0:80  (see <a href="http://www.rackaid.com/resources/how-to-disable-ipv6-in-apache-server/" rel="nofollow">http://www.rackaid.com/resources/how-to-disable-ipv6-in-apache-server/</a> )</p>
  
  <p>Here is one of my vhost files.</p>
  
  <pre><code>NameVirtualHost 0.0.0.0:80
  Listen 0.0.0.0:80
  &lt;VirtualHost 0.0.0.0:80&gt;
      ServerName www.domain.us
      ServerAlias domain.us
      ServerAdmin email@domain.us
