Hi Geoffrey,

the problem is with the [=] color. You know black on black, and you don't see it.

You should be able to change that from Template Options > Preset > settings

or by Custom CSS (Helix documenation tips)

.burger-icon > span, .offcanvas-active .burger-icon > span, #modal-menu-toggler.active .burger-icon > span {background-color: white;}

I assume that will be faster if I will do that, right?
