Hanamoto Sidebar at Bottom

Hello! I am using the Hanamoto theme for my food blog, and while making updates to the site, suddenly the sidebar is located at the bottom of the page (Except for the title of one widget). I have tried adjusting margin width, made sure “WordPress should correct invalidly nested XHTML automatically,” and tried adding </div></div> before the sidebar on each of the pages, however… it’s still not working. I’m pretty new to HTML and any help would be greatly appreciated! Thanks!!
