bootstrap fixed menu broke on scroll

Question

I have a bootstrap landing website, and there are one problem. When menu scrolled to bottom of page, it's just lost (mobile phone!). I don't know how. Other screen's like monitor work ok. But on mobile I have this problem.

Example

I have tried to load menu after website loading

$(window).load(function() {
    document.getElementById("hideAll").style.display = "block";
});

Styling like:

.navbar{
    height: 80px !important;
    max-height: 80px;
}

Nothing help me, menu still lost on scroll to bottom of page (on mobile phone)

检查@mediascreen中的浏览器兼容性。在该特定div类的css文件中添加@mediascreen 。
