When I go to my main domain: http://mydomain.com I get the apache default "It Works!" page. No content has changed and this was working last friday just fine. There is a wordpress installation on this domain with several subdomains hosting separate wordpress blogs. For example: subdomain1.mydomain.com works fine... subdomain2.mydomain.com works fine... mydomain.com doesn't work... All of these were working fine last week. No changes have been made... I have all entries at godaddy pointing to my external IP. I have port 80 forwarded to internal IP. I have the *. option enabled in ISPconfig for the site. Again, this was working fine last week How do I go about troubleshooting this? How can I tell what client or web directory its resolving and why?
