Remove Sidebar from all Coursepress items, but leave for blog

On my site at http://entreu.org, I want to remove all sidebar items for anything related to coursepress, but leave it for the blog so readers can search and view recent posts. You can go to http://entreu.org/courses/achieve-your-dreams/ to see the sidebar items. I am using the X Theme. It is on a multi-site install if that makes any difference.
