I've set up a subdomain and installed drupal on it. In doing this, I followed (http://tinyurl.com/93zm6) jtheory's suggestions as well as the instructions on test site workflow in the (http://drupal.org/node/27734) Drupal handbook.
In fact, I used those instructions to migrate the stuff from my personal domain to my client's domain, and the live site worked fine. I figured another 5 minutes for the subdomain setup. HA!
I repeated this to try to set up a test site on my client's subdomain (existing and tested first with a simple index page). The database connected fine as well. But there is simply no content on the test site; just a blank page. View source just gives empty HTML.
Finally, I used another domain that my client has on DH to see if I could get the site working there, and it worked just fine. So, what is up with the subdomain? Or is there something else that I'm missing? Ugh. I can't move forward until I figure this one out. I'll appreciate any help or suggestions you might have.
