I have a domain with Namecheap and hosting with 1and1. Forwarding is no problem - domain.com goes to the right page. The problem arises when I navigate to another page on the website, when it reverts to rootdomain.com/domain/blah.html.
On Namecheap I have the DNS transferred to 1and1, and I have provided the 1and1 nameservers. Any idea what could be wrong?
