I changed line 119 and 120 from:
wp_enqueue_script('jquery-ui-accordion', $this->plugin_path . 'js/jquery-ui-custom.min.js', array('jquery'), false, true);
wp_enqueue_script('jquery-ui-cookie', $this->plugin_path . 'js/jquery-cookie.min.js', array('jquery-ui-accordion'), false, true);
to
global $wp_version;
if (version_compare($wp_version, "3.1", ">=")) {
wp_enqueue_script('jquery-ui-google', 'https://ajax.googleapis.com/ajax/libs/jqueryui/1.8/jquery-ui.min.js', array('jquery'), false, true);
}
else {
wp_enqueue_script('jquery-ui-accordion', $this->plugin_path . 'js/jquery-ui-custom.min.js', array('jquery'), false, true);
}
wp_enqueue_script('jquery-ui-cookie', $this->plugin_path . 'js/jquery-cookie.min.js', array('jquery-ui-accordion'), false, true);
I SUSPECT it’s because I also have https://www.ads-software.com/extend/plugins/use-google-libraries/ installed, and they’re conflicting.
