Mobile responsive site display problem

Hi,
I have developed my website using mesocolumn theme. Thanks for the beautiful theme. I have a problem in displaying my website in mobile devices.

I enabled responsive option in customizer. everything is working fine. but in mobile devices , i can scroll the webpage horizontally. Because of this , if user scrolls the webpage horizontally towards left or right, some of the contents will get disappeared. I need help so that i can disable horizontal scroll in mobile devices. How can i disable horizontal scroll?

Thanks.
