After I configured ISPConfig and the websites into ISPConfig I rebooted my Linux machine and I started up ISPConfig_server.
I do not know what is going wrong. My websites are not accessible.
(
www.vanharten.net or vanharten.net or
http://www.vanharten.net or guido.vanharten.net or
http://guido.vanharten.net. None of these are accessible).
Who can help me?
