Hello?
Installed ISPConfig 3 properly.

Ubuntu Server 10.10

www.domain.com/phpmyadmin/ : working
www.domain.com/webmail/ : working
http://192.168.0.1:8080/ : working
http://192.168.0.1/webmail/ : working
http://192.168.0.1/phpmyadmin/ : working
FTP : working

www.domain.com:8080/ : NOT WORKING
webmail.domain.com/ : NOT WORKING
http://www.domain.com/index.html : NOT WORKING

http://www.domain.com/ : NOT SHOWN FIRST PAGE, redirect to http://www.domain.com/src/login.php (squirrel webmail)

I think my document root is /var/www/webmail/
But document root is ( /var/www) in /etc/apache2/sites-available/default.
I can't fix this.

HELP ME?
