Mobile menu doesn't expand Cornerstone 6 problem


With cornerstone version 6.1.4 the mobile menu on our site doesn’t expand anymore. With version 5.xx it still works. I don’t know how long this is going on.
The site:
I can’t find u plugin that is causing the problem.
The div .x-nav-wrap-mobile has an inline style height= 0. This keeps the menu closed.

Can you please help me?
