i recently just pointed one of my subdomain to ispconfig3 server. I have not setup any virtual site for this subdomain therefore it should be pointing to my default webpage which is http://220.127.116.11/
But strangely it is pointing to one of my virtual site with a totally different domain name.
I have looked into /etc/apache2/site-enabled/default and even added the line serveralias sub.domain.com
But it still doesn't work.
But one of my other sub domain which I used for setting up ispconfig is working fine. Any idea how to tackle this problem?
