为什么分页在Category.php上不起作用

有两个不同的类别“生命科学”和“普通实验室”，还有关于“生命科学”的子类别产品。现在“普通实验室”类别想要获取“生命科学”拥有的所有子类别和产品。代码在类别中。php。以下是全部代码：<代码>

Broken category pagination

出于某种原因，下面的代码一直工作到我到达第三页并给出404。不使用任何插件就可以修复它吗？<?php $temp = $wp_query; $wp_query = null; $wp_query = new WP_Query(\'cat=\'. $id .\'&posts_per_page=4&paged=\'.$paged); while ($wp_query->have_posts()) : $wp_query
