Sidebar problem

Hi,
the sidebar on my site is not in the correct position falls below the content. I found the solution on the site of the Plugin but unfortunately does not explain how to implement it, you could tell me where to put these codes: http://wpdeals.me/wordpress-deals-codex/codex/custom-theme-compatibility/

Using this theme: http://www.elegantthemes.com/demo/?theme=Glow

Greetings and thank you very much
