I have a problem with the mobile navigation menu (bootstrap) which doesn't open now and I don't understand where this problem comes from. I'm using WordPress and I haven't change anything about the menu. Could you help me please?
The mobile menu (under 800 pixel width) doesn't open.
The problem has come after I created a child theme.
It was a mistake from my browser, the problem is solved. Thank you @MikeStardust ! I just have uninstall and reinstall chrome and now it work.
