2、关于tag标签页做分页处理，点击页码有时会报404，解决方法如下：

/wp-includes/class-wp.php 的 handle_404()方法

// We will 404 for paged queries, as no posts were found.
if ( ! is_paged() ) {
   // Don't 404 for authors without posts as long as they matched an author on this site.
   $author = get_query_var( 'author' );
   if ( is_author() && is_numeric( $author ) && $author > 0 && is_user_member_of_blog( $author ) ) {
      status_header( 200 );
      return;
   }

   // Don't 404 for these queries if they matched an object.
   if ( ( is_tag() || is_category() || is_tax() || is_post_type_archive() ) && get_queried_object() ) {
      status_header( 200 );
      return;
   }

   // Don't 404 for these queries either.
   if ( is_home() || is_search() || is_feed() ) {
      status_header( 200 );
      return;
   }
}

原因是，页面加载时$wp_query->posts 查询结果为空数组，WP分页后默认会按404处理，修改代码如下：

// We will 404 for paged queries, as no posts were found.
if ( ! is_paged() ) {
   // Don't 404 for authors without posts as long as they matched an author on this site.
   $author = get_query_var( 'author' );
   if ( is_author() && is_numeric( $author ) && $author > 0 && is_user_member_of_blog( $author ) ) {
      status_header( 200 );
      return;
   }

   // Don't 404 for these queries if they matched an object.
   if ( ( is_tag() || is_category() || is_tax() || is_post_type_archive() ) && get_queried_object() ) {
      status_header( 200 );
      return;
   }

   // Don't 404 for these queries either.
   if ( is_home() || is_search() || is_feed() ) {
      status_header( 200 );
      return;
   }
}
//Tag页分页不显示404 --------------begin
else
      {
          if ( is_tag() ) {
              status_header(200);
              return;
          }
      }
//Tag页分页不显示404 --------------end

问题解决，同理，文章分类、自定义分类页如需做分页时，也需要做如上修改。
