[Theme: Onetake] Full Width Pages

I’ve been messing around with these for hours now and can’t figure out what I’m missing. I was able to remove the sidebar from view in this theme, but after using multiple resources, I am unable to locate the proper code to make my pages the full width of the page.

I’ve searched the forums as well as some google options, but none have worked. An example of the issue would be found here: ab0.307.myftpupload.com/?page_id=58

Any help would be greatly appreciated.
