When I enable my vhosts file (i.e. uncomment this line: Include /private/etc/apache2/extra/httpd-vhosts.conf) I am unable to reach localhost. I /am/ able to reach the last virtual host listed in my vhosts file:

<VirtualHost *:80>
  DocumentRoot "/Users/achan/Sites/epwbst"
  ServerName epwbst                                                                                                  
</VirtualHost>

<VirtualHost *:80>
  DocumentRoot "/Users/achan/Sites/pxproj"
  ServerName pxproj
</VirtualHost>

Typing pxproj in my browser brings up the expected web content. But I am unable to reach epwbst or localhost. If I re-comment the vhost line in my httpd.conf, I am able to reach local host (i.e. "It works!") but obviously am unable to reach my virtual hosts. I don't know how to continue troubleshooting this.

Why can't I reach localhost when I've got my vhosts turned on?
