Problem with burger menu

[MagnusE]

Hi!

Having a problem with the burger menu. When touching the icon on mobile the menu doesn't showing meaning it's not possible to navigate on our website from a mobile device. Have tried several devices and having the same problem. Any ideas what the problem might be? 

us.dbrisshoes.com (website can only be accessed from the US)

Thank you in advance
