非常简单的jQuery插件失败，控制台不显示错误

Question

我正在使用一个可以改变您的响应式导航的插件。我已经与其他网站一起使用并且效果很好： SlickNav jquery plugin

1）首先正确加载菜单

2）一秒后，仅显示HTML白色和菜单文字：

Chrome和Firefox控制台不显示错误......所以一切正常。

当然，我正在使用正确版本的jQuery并且脚本已正确加载。

发生了什么事？

非常感谢。

这是我调用脚本的文件：

响应式菜单调用是：

//Responsive Menu
        $(function(){
            $('.menu-responsive').slicknav();
        });
