My domain http://bretthowardsproul.com is active but the www version, www.bretthowardsproul.com , shows a blank screen.
I added this .htaccess but it doesn't change the results:
# Redirect www to no-www - via bit.ly/www-no-www
RewriteEngine On
RewriteCond %{HTTP_HOST} !^bretthowardsproul.com$ [NC]
RewriteRule ^(.*)$ http://bretthowardsproul.com/$1 [L,R=301]
I then tried test.bretthowardsproul.com and got a 404. So is it something in my .htaccess?
If not, do I need to do something with a CNAME? Is there something I can check in Firebug to see what's going on at www ?
Make sure the "www" CNAME exists for your domain, and is pointing to your @ record, otherwise "www" traffic won't go to the same place that your domain goes to without "www".
A quick google search should help you figure out how to add the CNAME to your registrar. For GoDaddy, this is helpful: http://www.google.com/support/a/bin/answer.py?answer=47610
