Increase width of Inovado wp Theme

Hi Guys,
It’s so unfortunate buyers of the popular inovado wordpress theme cannot get assistance from the authors of the theme when it even comes to even the slightest customization where you just have to copy and paste simple codes.

Anyway, i would like to know whether if someone can sort me out by checking on my website in order to guide me on how to increase the width the theme or website . Am actually not happy with the white wide background space at both the left/right side of the site.

I would like to extend the width of the site to enable my website content have a wide coverage of the website.

Thanks
