title: TypeError: jQuery.easing[jQuery.easing.def] is not a function
body: <p>I have one slider on the same page which is using jQuery version <strong>jquery-1.7.1.min.js</strong>, and on the same page I'm using the <strong>Contact Form-7</strong> and it uses <strong>[my site url]/wp-includes/js/jquery/jquery.js?ver=1.11.1</strong>. This both jQuery conflict with each other.</p>
  
  <p>I also de-register the jQuery of <strong>Contact Form-7</strong>, then when I click on send button it will reload the whole page. I don't want to reload the whole page on contact form-7's button click.</p>
