content and sidebar are gone!

I need serious help! Today while I was putting in ads for a friend, the content and right sidebar disappeared on me. I have no idea what I did, or how to fix it. I tried using other themes, and some of them have no change, while some are still missing the right sidebar. Here is the web address. https://www.familytravelsuite.com I appreciate all the help I can get with this issue! When I saw the content missing, it was hard NOT to freak out.
