I have the same problem as described in this post. Domain mapping purchased, nameservers changed, but myblog.worpress.com shows up in the URL instead of myblog.org.
The domain diagnostic tool told me this:
Oops, No Primary Site Set
There is no primary domain set for myblog.wordpress.com. This means that although myblog.org will forward to the site, myblog.org will appear in the browser address bar. To learn more about setting a primary domain, please see our documentation.
This is not what's happening. If I DO change the primary site to myblog.org, I get a redirect loop. The loop happens immediately after changing, and goes away immediately after changing back. Do I have to wait a while for it to work correctly? Is something broken, or did I mess up the configuration?
Thanks!
The blog I need help with is ctkreligioused.wordpress.com.
