How to fix the width after removing sidebar on one page?

You need to edit your stylesheet. Right now, it is likely set up to display the “main” content only to a specific width. The sidebar is set to be a certain width on the right. You need to find the right sections of your style.css file and add the two numbers together to make it stretch to fill the whole page.

Here is where you need to start. (I think)

.contentLayout .content
border:0 none;
float:left;
margin:0;
overflow:hidden;
padding:0;
position:relative;
width:69%;

Changing the obvious will probably just bork the layout on the rest of your pages. I think it might involve adding another div class specific to just the page template you are using for the forum.

Yes exactly of i did that it would blow out the other pages so how or what would the code be that i would need to add so it works just for the forum page?

I have the same problem, how do you fix it?
