Hi Mike,
I checked console and there are some js errors.

Please change your js script in Header > JS from
jQuery(document).ready(function($) {
if ( $('body').hasClass('x-one-page-navigation-active') ) {
$(function(){
$('.x-nav-tabs-item').on('click touchstart', function() {
setTimeout(function() {
$(window).trigger('resize');
}, 500);
});
});
}
to this
jQuery(document).ready(function($) {
if ( $('body').hasClass('x-one-page-navigation-active') ) {
$(function(){
$('.x-nav-tabs-item').on('click touchstart', function() {
setTimeout(function() {
$(window).trigger('resize');
}, 500);
});
});
}
});
Thanks
