wordpress coinlider不工作

I'm developing my customing wordpress theme and I want to create a featured content slider on the homepage so I installed the coinslider wordpress plugin, but there's no featured post. I'm quiet new to wordpress development so forgive my ignorance if the answer is obvious. I included the functions.php and my header.php is well linked to jquery. Why is this not working people? Please help

Did you know that by default, Wordpress loads jQuery with noConflict?

Basically, you're stuck with 2 options:

jQuery:

jQUery(document).ready(function(){
    // code using jQuery.fn
});

or (function($))(jQuery):

(function($){
    // code using $.fn
})(jQuery);
