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!:smile:

OK looks like I was able to turn off the boxes, so how do I have the text on the pages go all the way to the right? Thanks.

Admin - Configuration - Layout Settings - Column Right Status - Global

Ok so i did that, and it worked, but now its pushing everything to the right completely, like this:

How do i get it to look right?
Thanks so much!

your left side box is set to 300 px , you want to change that to 150px from admin area .
