Please check your css/custom.css, there are some issues:
.footer-lr-outer {
background: #ffffff none repeat scroll 0 0;
margin-bottom: 0 !important;
margin-left: -150px;
margin-right: -150px;
padding-left: 176px;
padding-right: 150px;
}
.footer-lr-outer {
background: #d9d9d9 none repeat scroll 0 0;
padding-bottom: 40px;
padding-top: 40px;
}
.footer-lr-outer, .footer-a-outer {
margin-left: -150px;
margin-right: -150px;
padding: 40px 50px;
}
Disable the footer and the scrollbar is hidden, therefore it depends on your footer code!
