Remove bottom border

EXAMPLE

You can see a white border at bottom of page.

It is also on every other page only not stretched.

Any solution?

Thanks.

UPDATE: We managed to fix the homepage with:

/* Change Background, Border, Font/Color of footer*/
footer#footer .colophon {
background:     none repeat scroll 0 0 #7ec247;
border-top:     0px solid #7ec247;

position:relative;
top: 10px;

color:          #000000;
padding:        0;
}

and the example page still contains white bar at bottom.
