Hi,

I had similar issues trying to set rewrites in Joomla up, heres how I fixed it:

gedit /etc/apache2/sites-available/www.domain.com.vhost

(lines 1 to 5)

<Directory /var/www/www.domain.com>
    AllowOverride All
    Order Allow,Deny
    Allow from all
</Directory>

(lines 23-34)

    <Directory /var/www/www.domain.com/web>
		Options Indexes FollowSymLinks Includes ExecCGI
		AllowOverride All
		Order allow,deny
		Allow from all
    </Directory>

    <Directory /var/www/clients/client1/web1/web>
		Options Indexes FollowSymLinks Includes ExecCGI
		AllowOverride All
		Order allow,deny
		Allow from all
    </Directory>

Save your file and close.
Restart apache - sudo /etc/init.d/apache2 restart

Hope this helps

Mark.
