Space at bottom of page?

See below an image of my footer - where my edited copyrights are.
For some reason I have a space underneath my footer where my background image won't reach - despite the fact that the image is large enough to cover the entire height of the background.

Do you have any ideas as to what caused this and how I could fix it?

Check if body element has padding or margin.
