wwwCustomDomainIssue
If you are using a custom domain, your BlogSpot address will only redirect to that domain if it does not have "www" at the beginning. I.e. both xxxxx.blogspot.com and www.xxxxx.blogspot.com will display the blog correctly, but only the former will appear with your custom domain name.
