It is a very weird thing. The post info shows on the home page. The sidebars are identical. THe mark-up is showing on the single post pages but the info is not there. Here's the single post page with the widget: http://www.mamapop.com/2013/01/hey-girl-ryan-gosling-wants-to-cast-you-in-directorial-debut-how-to-catch-a-monster.html
(the info is selected to show - as it is on the home page).
