LatinZoneMagazine on "[Theme: Asteria Lite] Sidebar not showing widgets."

I have widget visibility from Jetpack and have set it to show on post pages. The widgets are still not showing, neither is my twitter feed which I added in a text box. As a matter of fact, the sidebar is not showing at all. I understand it will not show on pages, but is supposed to show on post. Can you help me?
