Hi,

5 days gone, and no answer, very disappointing :(

Apology for the delay. You have changed the header layout and this is why offcanvas was not showing. Please create a new menu for offcanvas and select it in the offcanvas module.

Thanks for the hint. If i enable the Off Canvas with the Main menu there should be something displayed. But I see only blank menu.

Please take a custom.css file under css folder and add this

@media (min-width: 320px){
    .navbar-collapse {
        display: flex !important;
        flex-basis: auto;
    }
}
