I successfully changed the name servers at GoDaddy from WordPress.com to BlueHost, and was able to use it for a few hours. But then I went to my WordPress.com domain panel and deleted the mapping there --- I know I don't get a refund on that, that's fine.
But now I can't get to the new wordpress install at BlueHost, I am stuck with:
"Domain mapping upgrade for this domain not found. Please log in and go to the Domains Upgrades page of your blog to use this domain"
And it wants me to long in to wordpress.com and do... IDK what... I don't want to rebuy the mapping, because I don't want to point to wordpress.com... yet somehow wordpress.com is blocking or rerouting my bluehost hosting...
my domain is:
