Menu in cell. and tablet

Good evening.
In the simple site of our association (quadrantearte.it) we use the beautiful theme Astrid (free) and the plug-in “Max Mega Menu”.
I’m the administrator and I’ve noticed that, while on PCs the display of the menu is regular, on tablets and cell phones, instead of the little lines symbol of the menu, an exclamation point and a question mark appear and blink.
It’s clear that they are signaling me an error but I don’t understand how to solve it.
Can you help me? Thank you.

Hi,

Thank you for contacting us. I am happy to help with your queries.

Try adding this CSS code to Appearance > Customize > Additional CSS from dashboard.

    @media only screen and (max-width: 1024px) {
      .site-header .btn-menu {
        display: none;
      }
      #mainnav-mobi,
      #mega-menu-wrap-primary, 
      .mega-menu-toggle {
        display: block !important;
      }
    }

Ok, thanks; the menu problem has been solved, but now on mobiles and tablets the header area displays the default theme image that I changed: see the attached grab.
Is there a solution?

Thanks again.

You’re welcome!

Have you enabled separate image for header section on mobile screen?

The setting is located under Customize > Header area > Header Media.
