不幸地the_posts_navigation() 函数对我无效。当我点击“老帖子”时，它会显示“404页，我不知道为什么我的代码不起作用。”。

这是代码-

<div class="row">
    <?php while ( have_posts() ) : the_post(); ?> 
    <div class="col-md-3 thumbnailu">
        <a class="thmb" href="<?php echo get_post_meta ($post->ID, \'link_name\', true); ?>" target="_blank">
        <?php 
        the_post_thumbnail( \'website-image-size\', array( \'class\' => \'img-responsive\' ) ); 
    ?>

        <p class="caption"><?php the_title(); ?><br> 
        by <?php echo get_post_meta ($post->ID, \'author_name\', true); ?> </p>
        </a>
    </div>

<?php endwhile; ?>

<?php the_posts_navigation(array(
    \'prev_text\' => \'Older Posts\',
    \'next_text\' => \'Newer Posts\',
    \'screen_reader_text\' => \' \',
));
?>

即使我使用previous_posts_link() 作用
