页面导航不工作的自定义帖子类型

我整夜都在努力使这个工作，但似乎我找不到问题。我正在使用Bootstrap来制作一个新的主题，并且伴随着它，我有一小段用于自定义页面导航的代码，它似乎与基本的wordpress帖子列表一起工作得很好。

但是我已经添加了一个新的自定义帖子类型叫做画廊，我找不到一个解决方案，如何列出所有的帖子在画廊自定义帖子类型和使分页工作。到目前为止，我已经创建了一个名为archive-galleries.php的新文件，它列出了所有具有画廊自定义帖子类型的帖子，但它不会转到第二个页面。我得到错误404 not found .

这是archive-galleries.php页面的代码

<?php get_header(); ?>
<?php get_sidebar('top'); ?>
<div class="row">
    <div class="span8">
    <?php the_post(); ?>
    <h3 class="text-error"><?php _e('Latest image galleries', 'vt-translate'); ?></h3>
    <?php $count = 0;
    $paged = intval(get_query_var('paged'));
    $paged = ($paged) ? $paged : 1; 
    $query_arguments = array(
    'post_type' => 'galleries',
    'posts_per_page' => 4,
    'paged' => $paged,
    );
    // Query posts
    query_posts( $query_arguments );
     while ( have_posts() ) : the_post();
    $open = !($count%4) ? '<div class="row">' : '';
    $close = !($count%4) && $count ? '</div>' : '';
    echo $close.$open;
    ?>
        <div class="span2">
            <a href="<?php the_permalink() ?>">
                <img class="thumb" data-src="holder.js/160x250" alt="<?php the_title(); ?>" src="<?php bloginfo('template_url'); ?>/inc/timthumb.php?src=<?php echo get_post_meta($post->ID, 'thumb', true); ?>&h=250&w=160&zc=1" />
            </a>
            <div class="clearfix"></div>
            <h6>
                <a href="<?php the_permalink() ?>"><?php trim_title(); ?></a>
            </h6>
        </div>
    <?php 
    $count++;
    endwhile; 
    echo $count ? '</div>' : '';
    ?>
    </div>
    <div class="span4">
            <?php get_sidebar('pageright'); ?>
    </div>
</div>
<div class="pagination pagination-centered">
    <?php page_navi(); ?>
</div><!-- #nav-below -->
<?php get_sidebar('belownavigation'); ?>
<?php get_footer(); ?>

下面是我用于分页的自定义代码，位于functions.php文件中:

//Wordpress page navigation with numbers
function page_navi($before = '', $after = '') {
    global $wpdb, $wp_query;
    $request = $wp_query->request;
    $posts_per_page = intval(get_query_var('posts_per_page'));
    $paged = intval(get_query_var('paged'));
    $numposts = $wp_query->found_posts;
    $max_page = $wp_query->max_num_pages;
    if ( $numposts <= $posts_per_page ) { return; }
    if(empty($paged) || $paged == 0) {
        $paged = 1;
    }
    $pages_to_show = 7;
    $pages_to_show_minus_1 = $pages_to_show-1;
    $half_page_start = floor($pages_to_show_minus_1/2);
    $half_page_end = ceil($pages_to_show_minus_1/2);
    $start_page = $paged - $half_page_start;
    if($start_page <= 0) {
        $start_page = 1;
    }
    $end_page = $paged + $half_page_end;
    if(($end_page - $start_page) != $pages_to_show_minus_1) {
        $end_page = $start_page + $pages_to_show_minus_1;
    }
    if($end_page > $max_page) {
        $start_page = $max_page - $pages_to_show_minus_1;
        $end_page = $max_page;
    }
    if($start_page <= 0) {
        $start_page = 1;
    }
    echo $before.'<ul>'."";
    if ($paged > 1) {
        echo '<li class="prev"><a href="'.get_pagenum_link().'" title="First">'.__('&laquo;','vt-translate').'</a></li>';
    }
    $prevposts = get_previous_posts_link('&laquo; Previous');
    if($prevposts) { echo '<li>' . $prevposts  . '</li>'; }
    else { echo '<li class="active"><a href="#">&laquo; Previous</a></li>'; }
    for($i = $start_page; $i  <= $end_page; $i++) {
        if($i == $paged) {
            echo '<li class="active"><a href="#">'.$i.'</a></li>';
        } else {
            echo '<li><a href="'.get_pagenum_link($i).'">'.$i.'</a></li>';
        }
    }
    echo '<li class="">';
    next_posts_link('Next &raquo;');
    echo '</li>';
    if ($end_page < $max_page) {
        echo '<li class="next"><a href="'.get_pagenum_link($max_page).'" title="Last">'.__('&raquo;','vt-translate').'</a></li>';
    }
    echo '</ul>'.$after."";
}
