Featured Images not displaying on Homepage

Hello Support!

I've currently installed a Child Theme of Business Services onto a fresh WP MultiSite install and I'm having some trouble getting the posts to display the featured images while on the homepage using the featured posts section.

You can see the website here: http://devhut.upcomingmedia.com

Any insight would be appreciated, as I'm a bit stumped as to why they don't show..

Cheers,

Upcoming Media
