[Theme: Catch-Box Free] How to disable responsive design?

Hi all,

I’m using a child theme of Catch-Box (free version) and I’m developing it locally. I want to disable responsive design. I’ve searched through Catch Themes’ support forums, but have found no solutions that work. I can’t post a question on their forums–to receive direct support you have to pay.

I’ve already incorporated some custom css, and I’ve gotten the site to look how I want it to. Hence to say, I want to keep the theme, but I want to disable responsive design.

So, does anyone know how to disable Catch-Box (free) responsive design?

Thanks!
