这是我网站上存档页面的代码，当我尝试打开此页面时，它会出现404错误，并且不会显示任何内容。此代码中是否存在阻止它的问题？我正在为存档内容使用自定义帖子类型插件。

<?php get_header(); ?>



<style type="text/css">
.b33 { float:left; width: 33%; padding-left: 25px; padding-top: 35px; }
.b33 img  { max-width:100%; border:8px solid #91B49C;float:left; height:200px; overflow:hidden;}

</style>
