We already updated CNAME of blog.thegreenteahouse.com to greenteahouse.wordpress.com, and would like to buy domain mapping. However when we entered "blog.thegreenteahouse.com" and hit "Add Domain to Blog", we kept on getting the error message as,
"This domain has already been mapped to a WordPress.com blog."
Look like we mapped it to grnteahouse.wordpress.com, and would like to delete that domain mapping. Can you help on this?
The blog I need help with is greenteahouse.wordpress.com.
