Problem z widgetami i pisaniem nowych postó i stron

Modyfikuję szablon simplicitybright i do jego plików chciałem dodać widgety…

utworzylem wiec plik FUNCTIONS.php i wkleiłem to:

<?php
if ( function_exists('register_sidebar') )
	register_sidebar();

	function sb_get_logo() {
		$default_logo = get_bloginfo('template_url')."/images/logo.png";
		$custom_logo = get_option('sb_logo');
		$logo = (empty($custom_logo)) ? $default_logo : $custom_logo;
		return $logo;
	}

function widget_observer_init() {
	if ( !function_exists('register_sidebar_widget') ) return;

	function widget_observer($args) {
		extract($args);
		$options = get_option('widget_observer');
		$wtitle = $options['title'];
		$wshow = $options['show'];

		echo $before_widget;
			wp_list_bookmarks("category_before=&category_after=&categorize=0&title_li=$wtitle&title_before=<h2>&title_after=</h2>&show_images=0&show_description=1&limit=$wshow");
			echo '<p><a href="' . get_bloginfo('url') . '/links">' . __('View All Links') . '</a> >></p>';
		echo $after_widget;
	}

	function widget_observer_control() {

		// Get options
		$options = get_option('widget_observer');
		// options exist? if not set defaults
		if ( !is_array($options) )
			$options = array('title'=>'Observer', 'show'=>'3');

			if ( $_POST['observer-submit'] ) {
				// Remember to sanitize and format use input appropriately.
				$options['title'] = strip_tags(stripslashes($_POST['observer-title']));
				$options['show'] = strip_tags(stripslashes($_POST['observer-show']));
				update_option('widget_observer', $options);
			}

			// Get options for form fields to show
			$title = htmlspecialchars($options['title'], ENT_QUOTES);
			$show = htmlspecialchars($options['show'], ENT_QUOTES);

			// The form fields
			echo '<p style="text-align:right;">
					<label for="observer-title">' . __('Title:') . '
					<input style="width: 200px;" id="observer-title" name="observer-title" type="text" value="'.$title.'" />
					</label></p>';
			echo '<p style="text-align:right;">
					<label for="observer-show">' . __('Show:') . '
					<input style="width: 200px;" id="observer-show" name="observer-show" type="text" value="'.$show.'" />
					</label></p>';
			echo '<input type="hidden" id="observer-submit" name="observer-submit" value="1" />';

	}

register_sidebar_widget(array('Observer', 'widgets'), 'widget_observer');
register_widget_control(array('Observer', 'widgets'), 'widget_observer_control', 300, 200);

}

add_action('widgets_init', 'widget_observer_init');

if ( function_exists('register_sidebar') ) {

 	 register_sidebar(array(
    	'name'=>'strony',
        'before_widget' => '<div id="%1$s" class="widget %2$s">',
        'after_widget' => '</div>',
        'before_title' => '<h2>',
        'after_title' => '</h2>',
    ));

	register_sidebar(array(
    	'name'=>'kategorie',
        'before_widget' => '<div class="bb-kat widget-kat">',
        'after_widget' => '</div>',
        'before_title' => '<h2>',
        'after_title' => '</h2>',
    ));

	register_sidebar(array(
    	'name'=>'menu_top',
        'before_widget' => '<div>',
        'after_widget' => '</div>',
        'before_title' => '<h2>',
        'after_title' => '</h2>',
    ));

}

?>

do pliku SIDEBAR.php to:

<div id="sidebar">

<div class="sidelist">
<?php dynamic_sidebar('strony'); ?>
</div>

<div class="sidelist">
<?php dynamic_sidebar('kategorie'); ?>
</div>
</div>

wszystko sie wyswietla ale od tego czasu pokazują mi się błedy przy budowaniu nowego postu lub strony o takiej treści:

Warning: Cannot modify header information – headers already sent by (output started at C:\Program Files\WebServ\httpd\aktywni\wp-content\themes\simplicitybright\functions.php:1) in C:\Program Files\WebServ\httpd\aktywni\wp-includes\classes.php on line 1601

Czy moge prosić o pomoc w wskazaniu błlędu, rozwiązania, co zrobilem zle?

ewentualnie jak powinienem dodac poprawnie widgety ?

szukalem troche po CODEX ale nie znalazlem rozwiązania problemu innego niż to wyzej…
