Sidebar Widget Content shifted off page

All of a sudden overnight, the sidebar content of my website disappeared from the sidebar column to the bottom of the page into the blue background and I can’t get it back to where it belongs. The sidebar was built with Voyage Theme widgets and has been working faithfully for several years. Why did this shift all of a sudden and how do I get it back to the sidebar column. WordPress 3.9.2 running Voyage Theme theme. http://www.coloradotravelconnection.com
