Hamburger menu not opening after I created slick section

[Ultron]

After I uploaded a section for continuous image slider my hamburger menu stopped working on those pages where I uploaded the section on a page. How can I make them work both?

I uploaded this code -

for multiple slick section 

$(".customslick").not('.slick-initialized').slick({
slidesToShow: 2,
slidesToScroll: 1,
autoplay: true,
autoplaySpeed: 0,
speed: 8000,
pauseOnHover: false,
cssEase: 'linear',
responsive: [

{
breakpoint: 767,
settings: {
slidesToShow: 1,
}
}
]
});
