Hi, I am new to this so please forigive. I have read the previous threads about removing the side boxes, but what I did didnt seem to help, or I am doing it wrong. here is my link

I am trying to remove all 3 boxes on the right completely, the Sponsors, search, and "have you seen". I didnt seem to see those in the back end, I went to the layout-box controller and turned everything off on the whole bottom and those 3 are still there. Then I want to be able to make all my text on those pages go all the way over, not to stop where the "invisible" boxes are.

Thanks for your help, looking forward to learning this!
