I have exactly this problem, I think. I was setting up my first blog, made a mistake and started a new one, but Google only finds the first, wrong one. I've made the new, correct blog (http://piddingtonpantry.wordpress.com/) the primary blog, and made the old, wrong blog (http://hazelcoleman.wordpress.com/2012/10/24/piddington-christmas-market/) private and hidden. I've also cleared my history and my cache and forced a refresh. But Google still finds the wrong blog. People are asked to sign into WordPress to view the wrong blog, as it's private, but even when I type the whole correct URL into Google, it produces no results. The two blogs originally had the same name (The Pantry), so I was wary of deleting the wrong blog, in case I also lost the correct blog. Please can someone help me?
