Find this line in your stylesheet.css

.leftBoxContainer, .rightBoxContainer { background-image: url(../images/sidebox-footer.jpg); background-repeat: no-repeat; background-position: center bottom; margin: 0.5em 0 1em; padding-bottom: 9px; }

and after it add this line:

#blanksidebox {background: none;}
