Hello Baden, Thank You this is works. I just delete these 3 row
wp_deregister_script('jquery');
wp_register_script('jquery', 'http://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js', false, '1.4.4');
wp_enqueue_script('jquery');
in the beginning of my function.php and now works great.
The link which you give was useful for me. Thank you again and have a nice day. 🙂
