I'm creating a new post, have saved a draft I'm editing, and click on "Preview" - and it 404s me, saying it can't find the page. The draft is showing up under All Posts in my dashboard, but it insists it can't find the preview. I was hoping I'd find a bunch of recent posts here from people with similar problems (as has happened before when there's been some server issue that would be resolved in time), but not this time. Any ideas?
The blog I need help with is cubiksrube.wordpress.com.
