Widget Sidebar arrangement stuck

Hey everyone, I just imported my blogger.com blog to wordpress, and despite the sidebar.php and functions.php looking good, I cannot drag and drop my widgets in the sidebar arrangement screen in the presentation menu.

Here’s what the sidebar.php looks like:

<div id="sidebar">
<?php if ( !function_exists('dynamic_sidebar')
|| !dynamic_sidebar() ) : ?>
<h4>Categories</h4>
<div class="navigate">
<ul>
<?php wp_list_cats('sort_column=name&&hierarchical=1'); ?>
</ul>
</div>
<h4>Archives</h4>
<div class="navigate">
<ul>
<?php wp_get_archives('type=monthly'); ?>
</ul>
</div>
<h4>Blogroll</h4>
<div class="navigate">
<ul>
<?php get_linksbyname('Blogroll', '<li>', '</li>', '', FALSE,
'rand', FALSE, FALSE, 10); ?>
</ul>
</div>
<?php endif; ?>
</div>

here’s the functions.php:

<?php
// Widgets
if ( function_exists('register_sidebar') )
register_sidebar(array(
'before_widget' => '',
'after_widget' => '</div>',
'before_title' => '<h4>',
'after_title' => '</h4><div class="navigate">',
));
function widget_mytheme_search() {
?>
<h4>Search</h4>
<div class="navigate">
<form method="get" id="searchform" action="<?php bloginfo('home'); ?>/">
<input type="text" value="<?php echo wp_specialchars($s, 1); ?>" name="s" />
</form>
</div>
<?php
}
if ( function_exists('register_sidebar_widget') )
register_sidebar_widget(__('Search'), 'widget_mytheme_search');
function widget_mytheme_links() {
?>
<h4>Linkage</h4>
<div class="navigate">
<ul>
<?php get_linksbyname('', '<li>', '</li>', '', FALSE, 'rand', FALSE, FALSE, -1); ?>
</ul>
</div>
<?php
}
if ( function_exists('register_sidebar_widget') )
register_sidebar_widget(__('Links'), 'widget_mytheme_links');
function widget_mytheme_pages($args) {
extract($args);
$options = get_option('widget_pages');
$title = empty($options['title']) ? __('Pages') : $options['title'];
?>
<h4><?php echo "$title" ?></h4>
<div class="navigate">
<ul>
<?php wp_list_pages('sort_column=menu_order&title_li='); ?>
</ul>
</div>
<?php
}

?>

thanks so much for the future help everyone.
