I'm new to WordPress, so please bear with me. I've setup WordPress on my site and I've modified the htaccess file in the root of the site to point to my wordpress installation. I've installed a new theme and if I go to http://www.alternatetomorrow.com it redirects to the correct direct with the new theme. However, if I drop the www. part, i.e. http://alternatetomorrow.com, it still redirects to the correct location, but the site comes up with the original default theme that WordPress displays when installed. I've been digging through the settings in WordPress, but I can't seem to find what I need to change to make this display correctly.
FYI, I've tried this in Chrome and IE8 and I've cleared the cache in both browsers, but nothing changes.
What am I missing?
