Search Listings Widget

When using the “search listings widget” – the page that displays the search listings is showing a sidebar that is actually falling below the page. You can try it out here: http://www.hardincountykyrealestate.com/blog/
It would be fine to not have a sidebar show up on the page that displays the search. Any ideas on a fix? Thank you!
