基本上，除了顶级页面（例如，类别、归档、单篇文章、自定义文章类型等），所有内容都可以正常工作。

我有3个自定义帖子类型和4个自定义分类法（每个自定义分类法分别附加到一个帖子类型，还有一个分类法附加到所有帖子类型）。以下是这两个项目的设置：

register_taxonomy(
    \'newsroom-topics\',
    array ( 0 => \'news-post\',),
    array (
        \'hierarchical\' => true, 
        \'label\' => \'Newsroom Topics\',
        \'show_ui\' => true,
        \'query_var\' => true,
        \'rewrite\' => array(\'slug\' => \'/\'),
        \'singular_label\' => \'Newsroom Topic\'
    ) 
 );

register_post_type(
    \'news-post\',
    array(  
        \'label\' => \'Newsroom Posts\',
        \'description\' => \'\',
        \'public\' => true,
        \'show_ui\' => true,
        \'show_in_menu\' => true,
        \'capability_type\' => \'post\',
        \'hierarchical\' => false,
        \'rewrite\' => array(\'slug\' => \'newsroom\'),
        \'query_var\' => true,
        \'has_archive\' => true,
        \'exclude_from_search\' => false,
        \'menu_position\' => 5,
        \'supports\' => array(\'title\',\'editor\',\'excerpt\',\'trackbacks\',\'custom-fields\',\'comments\',\'revisions\',\'thumbnail\',\'author\',\'page-attributes\',\'post-formats\',),
        \'taxonomies\' => array(\'content-type\',\'newsroom-topics\',),
              \'labels\' => array (
              \'name\' => \'Newsroom Posts\',
              \'singular_name\' => \'Newsroom Post\',
              \'menu_name\' => \'Newsroom Posts\',
              \'add_new\' => \'Add Newsroom Post\',
              \'add_new_item\' => \'Add New Newsroom Post\',
              \'edit\' => \'Edit\',
              \'edit_item\' => \'Edit Newsroom Post\',
              \'new_item\' => \'New Newsroom Post\',
              \'view\' => \'View Newsroom Post\',
              \'view_item\' => \'View Newsroom Post\',
              \'search_items\' => \'Search Newsroom Posts\',
              \'not_found\' => \'No Newsroom Posts Found\',
              \'not_found_in_trash\' => \'No Newsroom Posts Found in Trash\',
              \'parent\' => \'Parent Newsroom Post\',
),) );

更新时间：

因此，在寻找了一段时间为什么会发生这种情况后，我刚刚发布了这篇文章，我发现了问题所在。在阅读设置中，我的首页被设置为显示为静态页面，当我将其更改回默认页面时，一切正常。
