For the past year, I've been using the subdomain version of WPMU on GoDaddy despite their claims that it won't work on their servers. This is how I did it if you want some background.
It's been fine this whole time, but recently in the past couple of months I noticed the styles missing from the subdomains. I'm not sure when this happened or who's fault it is, GoDaddy's or WordPress 3.0. My main site can use the themes fine and I can see them in the preview section, but when I go the backend of one my subdomains, the previews no longer work but it still says that there is a theme applied.
I even completely reinstalled Wordspress 3.0 and set it up according to the directions at GoDaddy, http://help.godaddy.com/article/6143, but still no luck.
Is there some way I can trick my installation into working? I really don't want to use the subfolder option. Maybe editing the .htaccess to show the subdomains where the themes are at? I have no idea where to start.
