Problem with virtual host?

[cuss]

are you using nat?
if yes, do this:

/etc/init.d/ispcp_daemon stop
cd /etc/ispcp/apache/parts/
sed -i "s/{IP}/YOUR.INTERNAL.IP.HERE/g" *
mysql -u root -p
mysql> USE ispcp;
mysql> UPDATE `domain` SET `domain_status` = 'change' WHERE `domain_status` = 'ok';
mysql> UPDATE `subdomain` SET `subdomain_status` = 'change' WHERE `subdomain_status` = 'ok';
mysql> UPDATE `domain_aliasses` SET `alias_status` = 'change' WHERE `alias_status` = 'ok';
mysql> UPDATE mail_users SET status="toadd" where status="ok";
mysql> quit
