我有一个名为blog的自定义帖子，我正在使用一个带有url的页面-slug blog，带有显示博客配置单元的自定义模板。
这是我在模板文件中使用的查询：
global $wp_query;
$wp_query = new WP_Query( array( \'post_type\' => \'blog\', /*\'cat\' => $cat_id, */\'orderby\' => \'date\', \'posts_per_page\' => 2, \'paged\' => $paged ) );
if ($wp_query -> have_posts()) {
while ($wp_query -> have_posts()) {
$wp_query -> the_post();
echo \'<div class="f4">\';
echo \'<div class = "left">\';
echo \'<a href = "\'; the_permalink(); echo \'">\';
echo \'<div class = "image">\';
the_post_thumbnail(\'home-thumbnail\');
echo \'</div>\';
echo \'</a>\';
echo \'</div>\';
echo \'<div class = "right">\';
echo \'<a href = "\'; the_permalink(); echo \'">\';
echo \'<h3>\'; the_title(); echo \'</h3>\';
echo \'</a>\';
echo \'<div class = "post-date">Posted on: \'; echo get_the_date(); echo \'</div>\';
the_excerpt();
echo \'</div>\';
echo \'</div>\';
};
};
wp_reset_postdata();
// wp_reset_query();
?>
</div>
</div>
<?php echo \'<div class = "wrap blog-pagination">\';
the_posts_pagination( array( \'mid_size\' => 2, \'screen_reader_text\' => __( \' \', \'textdomain\' ), \'prev_text\' => __( \'< PREVIOUS\', \'textdomain\' ),
\'next_text\' => __( \'NEXT >\', \'textdomain\' ), ) );
echo \'</div>\'; ?>
我正在使用这个脚本来生成cpt-blog，以及博客的默认自定义分类法。

问题是分页链接不工作。我是说
/blog/page/2/ 最后是404页。
链接结构设置为：/%类别%/%postname%/并且必须保持这种方式。
