Complete newbie here, just experimenting and learning and already I have got muddled.

I had got a static front page, using Twenty Twelve, and that was fine. And then I changed mu mind, and wanted the blog page to be the home page. So I changed back - only not thoroughly enough it seems.

So now I have a post that shows up if I google from outside WP, or go in through the dashboard, but isn't there if I click on the "Posts" tab at the top - although the post title shows up in the sidebar under "Recent posts".

If anyone can unmuddle me, I'd be very grateful!
