Problems with sidebar display

Hello,
I have difficulties displaying my sidebar on EightyDays Theme. On my home page it goes perfectly on the right: http://architectontheroad.com, but when I go on other pages like my ABOUT page for example: http://architectontheroad.com/about-architect-on-the-road/, the sidebar goes on the left, and under the content of the page!! I tried everything but can’t get to make it on the right side next to the content! Can I get some help please, I could not find help anywhereelse!
Thanks
Celine
