title: jQuery Wordpress Plugin Conflict - Uncaught Error
body: <p>I have some issues with plugins in WordPress.</p>
  
  <p>Yesterday when I installed WooTicket Studio plugin, it has conflicts with another previously installed plugin, the Essential Grid.</p>
  
  <p>He's not making requests when asked.</p>
  
  <p>Debugging the code I realized that he is not able to run scripts, that appears on the screen :</p>
  
  <blockquote>
    <p>Uncaught Error: no such method 'instance' for menu widget 
        /wp-admin/load-scripts.php?c=0&amp;load%5B%5D=jquery-core,jquery-migrate,utils,jquery-ui-core,jquery-ui-widget,jquery-ui-mouse,thickbox,plupload,jquery-ui-draggable,jquery-ui-slider,jquery-touch-punch,iris,wp-color-picker&amp;ver=4.5.2</p>

  <p>Has anyone had this same problem ? How can I solve it?</p>
