No lateral column in Blog post?

Hello dears geo directory admin,

I installed geo plugin and geo theme. I don’t find the way to make appear a right or left column on normal blog article, like here (http://vente-achat-or.org/les-deux-regimes-fiscaux-sur-lor-dinvestissement-en-france/). It´s a full with article, no column.

I did had the “related listing” plugin in “sidebar primary” (Wp dashboard —appearance — widget) that understand this one should appear.
I uninstalled all plugin that could interfere (related with page design setting)

Any clue?
It’s look like a good theme but this is not that easy
