Hello,
You have 404 error for the js file http://prntscr.com/kgno75 It causes your issue. I see that you are using CloudFlare. Have you cleared CDN cache after the update?
Contact your hosting provider support or CDN support to find out why that file gives you 404 error. Because we checked the files and it is in the backend http://prntscr.com/kgnp7h
