PHP error in footer of admin

Hi mate,

I also encountered this error. The call_user_func_array() is calling a function that doesn’t exist any longer. Open your multi-image-upload.php and remove line 82.

/**
     * Initialize Multi_Image_Uploader
     */
    public function __construct()
    {
        $this->post_types = array('post', 'page');     //limit meta box to certain post types
        add_action('add_meta_boxes', array($this, 'add_meta_box'));
        add_action('save_post', array($this, 'save'));
        add_action('admin_enqueue_scripts', array($this, 'enqueue_scripts'));

       //add_action('admin_print_footer_scripts', array($this, 'admin_print_footer_scripts'));

    }

That should do the trick.
