Search page doesn't work in the Motion theme

Hi all,

I’m having a problem with the Motion theme/search page. Every time I go for a search I can only be redirected to the homepage of the website.

The file about this search is called “searchform.php” and inside I find only this code:

<?php get_header(); ?>

<div id="search">
	<form method="get" id="searchform" action="<?php home_url(); ?>/">
		<p>
			<input type="text" value="<?php _e("Cerca nel sito...", 'motion_theme'); ?>" onfocus="if (this.value == '<?php _e("Cerca nel sito...", 'motion_theme'); ?>' ) { this.value = ''; }" onblur="if (this.value == '' ) { this.value = '<?php _e("Cerca nel sito...", 'motion_theme'); ?>'; }" name="s" id="searchbox" />
			<input type="submit" class="submitbutton" value="Cerca" />
		</p>
	</form>
</div>

Any other file (like search.php) isn’t in the theme’s package.. I made some simple changes to the pages but in that case I’m not able to understand what I need to do.

Please I’m looking for someone’s who can help me, thank you very much.
