Newstore theme sidebar

I’m using the Newstore theme and want to move the sidebar front from the right to the left and have it appear on the left on every page. I can change the background colour etc, but can’t see how to move it to the left. Yet on one of their demo stores, it shows a menu/sidebar on the left.

This is the demo store https://demo.themefarmer.com/newstore/

The page I need help with: [log in to see the link]
