Hello Marty,
Thanks for writing to us.
I checked your site, it seems that due to the color of the hamburger menu icon it is not visible. I would suggest you add this custom CSS code under X—>Theme option —>CSS to get rid of this.
@media(max-width:978.99px){
.x-btn-navbar.collapsed {
color: #ffffff;
}
.x-btn-navbar.collapsed:hover {
color: #ffffff;
}
}
Please feel free to change the color code as per your design.
The purpose of providing custom CSS is to show you how to add CSS code to your site. Writing custom CSS is outside the scope of our theme support. If you need more customization, you need to learn CSS and learn how to use the browser’s element inspector.
Hope it helps.
Thanks
