I accidentally changed URL for my blog. When I try to administer it, go to the Dashboard, just about anything, I get a Chrome error page: "Oops! Google Chrome could not find caroleggrace.com". The URL should be carolegrace.com (one "g"). Can't seem to find anywhere to change this now. And, I have a "linked blog" that is hidden, showing on my "My Blogs" page.
The blog I need help with is carolegrace.com.
