Hi,

When I login to your admin page by use the information you provided. I got 403 issue - check this image:

Is your admin page blocked IPs from some countries? Or are you using any security plugin?

If yes, let check and disable it for me. When I done, you can re-enable it.

Hi,

This issue caused by your menu is too long on those screens and it doesn't enough space to display in one row.

You can add more this code to Customize > Custom CSS to make it auto resize when screen is too small:

@media only screen and (max-width: 1169px){
    #navigation.header-11>.container, #navigation.header-10>.container {
    display: table;
    }
    .main-nav-social{ margin-right: 0; }
    #navigation .menu,
    #navigation.header-11 .penci-menu-wrap, #navigation.header-10 .penci-menu-wrap {
        display: none !important;
    }
    .penci-mobile-hlogo, #navigation .button-menu-mobile {
    display: inline-block;
}
    .penci-hlogo-center .penci-mobile-hlogo, .penci-hlogo-center #navigation.header-6 #logo{ float: none; margin: 0; position: absolute; left: 50%; top: 0; transform: translateX(-50%); -webkit-transform: translateX(-50%); z-index: 10; }
    #sidebar-nav { display: block; }
    #navigation, .sticky-wrapper:not( .is-sticky ) #navigation, #navigation.sticky:not(.sticky-active),
    .sticky-wrapper.is-sticky #navigation, .is-sticky #navigation.menu-item-padding, .is-sticky #navigation.menu-item-padding, #navigation.sticky-active, #navigation.sticky-active.menu-item-padding, #navigation.sticky-active.menu-item-padding{
        height: 60px !important;
    }
    #navigation .menu > li > a, .main-nav-social, #navigation.sticky:not(.sticky-active) .menu > li > a, #navigation.sticky:not(.sticky-active) .main-nav-social, .sticky-wrapper:not( .is-sticky ) #navigation .menu>li>a, .sticky-wrapper:not( .is-sticky ) .main-nav-social,
    .sticky-wrapper.is-sticky #navigation .menu>li>a, .sticky-wrapper.is-sticky .main-nav-social, #navigation.sticky-active .menu > li > a, #navigation.sticky-active .main-nav-social { line-height: 58px !important; height: 58px !important; }
}
