how can I fix my virtualhost setup after upgrading my ubuntu server to 10.04

Question

I recently updated my ubuntu server to 10.04 and my virtualhost setup no longer working correctly.

I host two sites from my server and before the update the addresses linked correctly to their respective sites, but afterwards both addresses link to the same site, even though I have not made any changes to sites-available and both sites are enabled.

My setup is like this:

In /etc/apache2/sites-available/ I have two configuration files: "www.site1.com" and "www.site2.com"

thes configuration files are setup as follows:

<VirtualHost *:80>
    ServerAdmin [email protected]
    ServerName  www.site1.com
    ServerAlias site1.com

    # Indexes + Directory Root.
    # DirectoryIndex index.html index.htm index.php
    DocumentRoot /home/www/www.site1.com/htdocs/

    # CGI Directory
    ScriptAlias /cgi-bin/ /home/www/www.site1.com/cgi-bin/
    <Location /cgi-bin>
            Options +ExecCGI
    </Location>

    # Logfiles
    ErrorLog  /home/www/www.site1.com/logs/error.log
    CustomLog /home/www/www.site1.com/logs/access.log combined
</VirtualHost>

in addition I have the following setup in /etc/apache2/ports.conf:

NameVirtualHost *:80
Listen 80

<IfModule mod_ssl.c>
    NameVirtualHost *:443
    Listen 443
 </IfModule>

The only clue I have is when I restart apache I get the following errors:

[warn] NameVirtualHost *:443 has no VirtualHosts
[warn] NameVirtualHost *:80 has no VirtualHosts

This may be way to simplistic, but have you run a2ensite to create the symlinks back to the site-available folders?

ie: a2ensite www.site1.com

If I remember correctly, the configuration files aren't read from sites-available, only from site-enabled (the symlinks from sites-enables to sites-available) and could be the source of your warnings because Apache is not seeing any VirtualHosts being created when the configuration files are read.
