Getting errors in Chrome Console

Hello,

I am using your theme on my site http://www.silkfactory.hr

I am using WP Rocket. I am using themes Combine JS Files, when I use the Combine JS Files from WP Rocket, the site menu and account slider breaks.

Problem is that I get many errors in the console, but I have not changed any code from the site and I am using minimal plugins because the theme itself has everything.

How can I fix the console errors?

Thanks
