Menu vanishes instead of collapsing on mobile and small windows

Somehow, the icon opening the menu on small screen sizes vanished from my site. I tried removing all custom css, and resetting all the header / menu settings, but I can’t get it back. This is the site. Any idea what happened there?

Hello,

This is because mobile menu button is white on white header background, but you can easily change button color with custom css code below:

.btn-menu {
    color: #000;
}

Best Regards!

Oh my, I feel stupid now. Thank you for your help!

You’re welcome,

And thanks for using our theme.

Bests!
