www.domain.tld and domain.tld are different

So I've got ISPConfig working on a rackspace cloud server on ubuntu 12 with apache2.

Right now, www.domain.tld and domain.tld are pointing to two different sites.

domain.tld shows a plain page with "It works!" and www.domain.tld shows the ISPConfig "Welcome to your website!" notice.

Unsure as to what I need to do get these pointing to the same site.

 

Can you post the www.domain.tld vhost?
