I believe the issue is that you replaces Template:Crl with your footer template. The footer template should be placed below Template:Crl. The main page columns float like infoboxes. So since there is space to the right of the left column, the footer tried to squeeze in there. Template:Clr is a dummy tag which doesn't attempt to squeeze to the side of floating content and thus prevents the content below it from doing so.
