Remove calling to right sider from 404 page
 

Hi,
my banner plugin has a problem in displaying banner in a properly way in 404 page, they suggest me to :
Remove calling of right sidebar form your theme option i.e edit 404.php and remove all right side bar code.
Really i i verify that i need only to "cut off" Last posts from right sidebar, rest of sidebar generate any faults.

Thnx
:)
