Hamburger menu appears as white box using child theme

Hamburger menu icon appears as white box using child theme instead of the three lines http://artobatours.com/ I can’t see what changes I’ve made have caused the change (works fine with sydney parent theme).

Hello there,

Please try these steps:

  1. Disable site optimization / code compression from your plugin
  2. Try to temporarily disable all custom CSS code in your child theme’s style.css

Let me know how it goes.
