自定义帖子类型单页显示完整空白

Question

你好我的wordpress主题的帖子类型listings单个帖子显示一个空白页面。但另外3个托管它的工作原理。 一个完整的空白偶数页面标题没有显示。

我试图通过以下方式解决问题：

1. WP_DEBUG设置为true
2. 删除分层
3. 设置error_reporting（-1）
4. 停用所有插件
5. 新设置主题

但所有这些步骤都已经过去了。

我的自定义帖子类型注册：

public function register_restaurant_listing()
{
    register_post_type('listings', array(
        'labels' => array(
            'name' => __('Restaurant listing', 'thefoody') ,
            'singular_name' => __('Restaurant listing', 'thefoody') ,
            'add_new' => __('Add New', 'thefoody') ,
            'add_new_item' => __('Add New Restaurant listing', 'thefoody') ,
            'edit' => __('Edit', 'thefoody') ,
            'edit_item' => __('Edit Restaurant listing', 'thefoody') ,
            'new_item' => __('New Restaurant listing', 'thefoody') ,
            'view' => __('View Restaurant listing', 'thefoody') ,
            'view_item' => __('View Restaurant listing', 'thefoody') ,
            'search_items' => __('Search Restaurant listings', 'thefoody') ,
            'not_found' => __('No Restaurant listings found', 'thefoody') ,
            'not_found_in_trash' => __('No Restaurant listings found in Trash', 'thefoody') ,
            'parent' => __('Parent Restaurant listing', 'thefoody') ,
        ) ,
        'public' => true,
        'show_ui' => true,
        'exclude_from_search' => true,
        'hierarchical' => true,
        'supports' => array(

        'menu_icon' => 'dashicons-megaphone'
    ));
