    I have a multie site setup, and I am trying to activate a theme. When doing so I get a nasty 500 error and the site (including admin dasboard for that site) are down.

    Server error
    The website encountered an error while retrieving http://localhost/blog.site.com/wp-admin/. It may be down for maintenance or configured incorrectly.
    Here are some suggestions:
    Reload this webpage later.
    HTTP Error 500 (Internal Server Error): An unexpected condition was encountered while the server was attempting to fulfill the request.

    I activated the logs and get this error:
    [10-Apr-2013 17:46:17 UTC] PHP Fatal error: Class 'Header' not found in /Applications/MAMP/htdocs/blog.site.com/wp-includes/widgets.php on line 324

    I traced the header class to my functions.php file for the theme where I am trying to register a widget:

    register_widget( 'Header' );
    register_widget( 'Search_Widget' );
    
    class Header extends WP_Widget {
    
    	function __construct() {
    		$widget_ops = array('description' => __( 'Displays the header.') );
    		parent::__construct('header', __('Header'), $widget_ops);
    	}
    
    	function widget( $args, $instance ) {
    		extract( $args );
    
    		// global $post;
    		global $categories, $cat_count, $top_level_cats, $top_level_count;
    
    		$categories = get_the_category($post->ID);
    		$cat_count = count($categories);
    
    		/* if the page requested is a post detail or category page */
    		if ( is_single() || is_category() ) {
    		/* set top level categories based on the nav */
    			$top_level_cats = array('brown', 'green', 'blue', 'red');
    			$top_level_count = count($top_level_cats);
    
    			for ( $i = 0; $i < $cat_count; $i++ ) {
    			/* if we're not in a parent category, then get the parent ID */
    			/* DISCLAIMER: we're only going 1 level deep here */
    				$slug = $categories[$i]->slug;
    				$parentID = $categories[$i]->category_parent;
    				if ( $parentID != 0 ) {
    					$parent = get_category( $parentID );
    				}
    
    				for ( $j = 0; $j < $top_level_count; $j++ ) {
    					if ( $parentID == 0 && $slug == $top_level_cats[$j] ) {
    					/* if it's a parent category and a top level category */
    						$slug = preg_replace("/-/", "_", $slug);
    						$banner = get_option( $slug . '_banner');
    						$name = $categories[$i]->name;
    						break 2;
    					} else if ( $parent->category_parent == 0 && $parent->slug == $top_level_cats[$j] ) {
    					/* if it's a child of a top level category */
    						$slug = preg_replace("/-/", "_", $parent->slug);
    						$banner = get_option( $slug . '_banner');
    						$name = $parent->name;
    						break 2;
    					}
    				}
    			}
    		}
    
    		if ( !$banner ) {
    		/* if banner was not set by the previous function, set it now */
    			$banner = get_option('banner');
    			$name = get_bloginfo('name');
    		}
    
    		echo "<div class=\"container\">\n";
    		echo "<a href=\"" . get_option('home') . "\"><img src=\"" . $banner . "\" alt=\"" . $name . "\"></a>\n";
    
    		wp_nav_menu( array( 'theme_location' => 'blog-menu', 'container' => false, 'menu_id' => 'menu', 'fallback_cb' => '', 'link_before' => '<span class="c">', 'link_after' => '</span><span class="r"></span><span class="b"></span>' ) );
    
    		echo "</div>\n";
    	}
    }
    
    class Search_Widget extends WP_Widget {
    
    	function __construct() {
    		$widget_ops = array('description' => __( 'New search widget for the right rail.') );
    		parent::__construct('search_widget', __('Search Widget'), $widget_ops);
    	}
    
    	function widget( $args, $instance ) {
    		extract( $args );
    
    		echo "<div class=\"pod wp-search\"><div class=\"hd\"></div><div class=\"bd\">\n";
    		include('searchform.php');
    		echo $after_widget;
    
    	}
    }

    I am completely baffled.

    I resolved this. Happens to be order of operations. so I moved the register_widget declarations below the classes and voila
