It seems conflicting with “calendarize it” plugin. There are an option the jQuery UI version to load in the frontend and backend, and by default it loads 1.9.0 on WP3.5 and higher. I’ve tried your suggestion at the other discussion in this forum by adding following html code :
jQuery(document).ready(function ($) { var themeUrl = iphormL10n.plugin_url + ‘/js/jqueryui/themes/smoothness/jquery-ui-1.8.24.custom.css’; $(‘head’).append(”);
