Full width not working – sidebar problem

Hi guys,

My website is http://novook.com

I’ve used the code you can find in http://presscustomizr.com/snippet/display-full-width-pages/ in order to make my website full width.

I used it in another website (dreamglish.com) and it worked perfect but I cannot find what is going on in the new website.

Actually I found the piece of code that makes the right sidebar be in the left, but If I change the css, then the sidebar takes extra space in the right and a scrool bar appear. It is very weird.

Any help please?

Thanks so much
