Space at bottom height: 100%

The URL I have installed modx on is http://www.forward-on.com/MMG/modx

However there is space at the bottom of the page even though the exact same code when not in modx does not produce the extra space>

Does anyone know how to get rid of the this extra space?

Thank you

For some reason this problem was fixed when I deleted my template and created a new one with the exact same content. Hope no one else gets this problem, was banging my head against a wall...
