I have a LAMP stack Wordpress multisite install setup using subdomains. It has 3 sites on it, two of which are working fine. I added my third site last night using the same settings as site number 2. All the DNS point to DO servers form my registrar. I have run tests on pingdom and modern.ie all check fine. The site loads on my iPad fine, but nowhere else. Site is http://waggingdogdesign.com. I have see articles on adding sites in the sites available folder, but it is not clear to me how to set that up since I have not had to use that so far.
