Scrolling

Hi,

I’ve just started to use Hueman Theme for my blog and really love it. Thanks for the theme and all the costumizing possibilities! I have just one problem with the theme and have no idea how to solve it. I can’t scroll the page with the mouse – just on desktop view – but when I’m in the admin, this problem doesn’t occure. Also on mobile, everything is fine. Would you give me any tip how to solve this problem?
