Critical: New blog posts no longer showing in listing or front page

For http://www.armchairarcade.com, I have a new blog post, which you can see with the direct link here: http://armchairarcade.com/perspectives/2015/02/04/videogame-feature-film-documentary-gameplay-now-exclusively-online-at-vimeo-on-demand/

Unfortunately, it’s not showing for non-logged in users on our front page (like blog posts always have). This appears to have happened after I upgraded to the latest version (the one that fixed the issue with the icons showing up).

Can you kindly help ASAP? I’ll give admin access in a private reply.
