White Space at the Bottom of My WordPress Site

Hi there,
I’m using the latest ColorMag Theme (by ThemeGrill) on WordPress 4.3.1

Of late, I don’t know what changes I made (not sure), now my web page is showing up a blank white space at the footer. No idea how to remove it. It looks quite odd and I would want to get rid of that asap.Please have a look at the footer part and suggest some idea to fix that. That’s my website ->
.

Any help would be appreciated, Thank You
