Widget Problem

Hallo Leute,
ich wollte in der functions.php Widgets einbinden, die ich für die Webseite benötige.
Im Netz habe ich mich schlau gemacht, aber ich habe ein kleines Problem.


Das steht in der functions:


<?php
add_action('after_setup_theme', 'theme_setup');




function theme_setup(){
    add_theme_support( 'post-thumbnails' );
    set_post_thumbnail_size(125, 125, true);
    add_image_size('slideshow', 800, 350, true);
    
    $args = array(
        'default-color' => '',
        'default-image' => get_template_directory_uri().'/img/hg3.jpg'
   &nbsp;);
    
    add_theme_support('custom-background', $args);
    
    register_nav_menus(array(
     'topnavi-user' => __('Top-Navigation-User', 'meinewpseite'),
     'topnavi-guest' => __('Top-Navigation-Guest', 'meinewpseite'),
     'primary' => __('Prim&auml;rnavigation', 'meinewpseite'),
     'links' => __('Links', 'meinewpseite'),




   &nbsp;));
    
    register_sidebar(array(
        'name' => 'Sidebar',
        'id' => 'main_sidebar',
        'before_widget' => '<aside id="%1$s" class="%2$s sidebar_widgets">',
        'after_widget' => '</aside>',
        'before_title' => '<h4 class="striped-line">',
        'after_title' => '</h4>'
   &nbsp;));
    
    register_sidebar(array(
        'name' => 'Footer',
        'id' => 'footer_sidebar',
        'before_widget' => '<div id="%1$s" class="%2$s footercol">',
        'after_widget' => '</div>',
        'before_title' => '<h5>',
        'after_title' => '</h5>'
   &nbsp;));




    register_sidebar(array(
        'name' => 'Artikel-ID',
        'id' => 'artikel_id',
        'before_widget' => '<div id="%1$s" class="%2$s box">',
        'after_widget' => '</div>',
        'before_title' => '<h5>',
        'after_title' => '</h5>'
   &nbsp;));




    register_sidebar(array(
        'name' => 'Slider',
        'id' => 'slider',
        'before_widget' => '<div id="%1$s" class="%2$s box">',
        'after_widget' => '</div>',
        'before_title' => '<h5>',
        'after_title' => '</h5>'
   &nbsp;));
    
    $args = array(
        'width' => 800,
        'height' => 350,
        'uploads' => true,
        'header-text' => false,
        'default-image' => get_template_directory_uri().'/img/slider1.png'
   &nbsp;);
    
    add_theme_support('custom-header', $args);
}








function infinite_scroll_init() {
add_theme_support( 'infinite-scroll', array(

'container' => 'contentMain',
'wrapper' => true,
'render' => false,
'posts_per_page' => false

        $this->WP_Widget('social_widget', __('Social Widget'), $widget_ops);
    }




    function widget($args, $instance){
        extract($args);
        echo $before_widget;
        
        $result = count_users();
