i can't find 'scrollto' anywhere in theme code. heres's i've found in theme's header.php @ least... still can't find put preventdefault

<ul class="navigation">                                 <?php if (has_nav_menu( 'header-menu' )) { ?>                                 <?php                                    $the_menu = array(                                     'theme_location'  => 'header-menu',                                     'container'       => 'ul',                                     'menu_class'      => 'menu',                                     'echo'            => true,                                     'fallback_cb'     => 'wp_page_menu',                                     'items_wrap'      => '%3$s',                                     'depth'           => 0                                    );                                     wp_nav_menu( $the_menu );                                 ?>                             <?php } ?>                             </ul> 

if it's problem default href behaviour should in function before scrollto place preventdefault should like:

$("yourmenulink").click(function(event) { event.preventdefault(); scrollto....  });
