Website width problem!

Ever since I updated SiteOrigin, when I enter Features service the website on smaller devices goes left and right. I tried disabling the feature and it works fine. I tried setting some CSS style to disable padding or margin to some elements, but nothing works.
The link to my website is: http://onepage.42studios.mk/. Try to resize browser and you will notice the scroll part on the bottom which makes the website go little to the right.
Anyone with the same problem?
