Version 2.0 Problems admin pages

I have the same problem after I updated the plugin. Please help!
I can’t toggle to expand or collapse anything in the editing page.

Hi,
Thanks for your feedback.
This is a simple problem from “statistics.js” file. Before the next update, please replace the following codes with current “admin/classes/class-charts.php” file:

<?php
if ( ! class_exists( 'wp_ulike_stats' ) ) {

	class wp_ulike_stats{
		private $wpdb;

		/**

		 */

		{
			global $wpdb;
			$this->wpdb = $wpdb;
			add_action('admin_enqueue_scripts', array($this,'enqueue_script'));
		}

		public function enqueue_script($hook)
		{
			if ( 'wp-ulike_page_wp-ulike-statistics' != $hook ) {
				return;
			}
			wp_register_script('wp_ulike_chart', plugins_url( 'js/chart.min.js' , __FILE__ ), array('jquery'), null, true);
