WP_QUERY与分页重定向到主页

Question

我有一个自定义帖子类型设置的自定义循环，还添加了分页。但是，当 /page /2将其加载到主页时。是什么原因造成的？

这是我的代码：

function viares_graduates () {
    $paged = ( get_query_var( 'paged' ) ) ? get_query_var( 'paged' ) : 1;
    $args = array (
        'paged' => $paged,
        'post_status' => 'publish',
        'post_type' => 'graduates',
        'posts_per_page' => 9, 
        'tag__not_in' => array( '76' ),
        'orderby'        => 'rand',
    );

    $loop = new WP_Query( $args );
while ( $loop->have_posts() ) : $loop->the_post(); 
//here my loop is displayed

endwhile;?>
<div class="pagination">
        <?php 
    echo paginate_links( array(
        'base'         => str_replace( 999999999, '%#%', esc_url( get_pagenum_link( 999999999 ) ) ),
        'total'        => $loop->max_num_pages,
        'current'      => max( 1, get_query_var( 'paged' ) ),
        'format'       => '?paged=%#%',
        'show_all'     => false,
        'type'         => 'plain',
        'end_size'     => 2,
        'mid_size'     => 1,
        'prev_next'    => true,
        'prev_text'    => sprintf( '<i></i> %1$s', __( 'Newer Posts', 'text-domain' ) ),
        'next_text'    => sprintf( '%1$s <i></i>', __( 'Older Posts', 'text-domain' ) ),
        'add_args'     => false,
        'add_fragment' => '',
    ) );
        ?>
    </div><?php 
wp_reset_postdata(); 
}
add_shortcode('viares_graduates', 'viares_graduates');

分页在前端正确显示，循环正常工作。您可以在此处查看： https://dev.viares.at/graduates/ 但是，当我单击下一页时（ https://dev.viares.at/graduates/页/2/）它重定向到 https://dev.viares.at/

帖子类型：

function custom_post_type() {
 

    $labels = array(
        'name'                => _x( 'Graduates', 'Post Type General Name', 'twentytwenty' ),
        'singular_name'       => _x( 'Graduate', 'Post Type Singular Name', 'twentytwenty' ),
        'menu_name'           => __( 'Graduates', 'twentytwenty' ),
        'parent_item_colon'   => __( 'Parent Movie', 'twentytwenty' ),
        'all_items'           => __( 'All Graduates', 'twentytwenty' ),
        'view_item'           => __( 'View Graduate', 'twentytwenty' ),
        'add_new_item'        => __( 'Add New Graduate', 'twentytwenty' ),
        'add_new'             => __( 'Add New', 'twentytwenty' ),
        'edit_item'           => __( 'Edit Graduate', 'twentytwenty' ),
        'update_item'         => __( 'Update Graduate', 'twentytwenty' ),
        'search_items'        => __( 'Search Graduates', 'twentytwenty' ),
        'not_found'           => __( 'Not Found', 'twentytwenty' ),
        'not_found_in_trash'  => __( 'Not found in Trash', 'twentytwenty' ),
    );
     
    $args = array(
        'label'               => __( 'Graduates', 'twentytwenty' ),
        'description'         => __( 'Reviews from Graduates', 'twentytwenty' ),
        'labels'              => $labels,
        'supports'            => array( 'title', 'editor', 'author', 'thumbnail', 'custom-fields', ),
        'hierarchical'        => false,
        'public'              => true,
        'show_ui'             => true,
        'show_in_menu'        => true,
        'show_in_nav_menus'   => true,
        'show_in_admin_bar'   => true,
        'menu_position'       => 4,
        'can_export'          => true,
        'has_archive'         => false,
        'exclude_from_search' => true,
        'publicly_queryable'  => false,
        'capability_type'     => 'post',
        'show_in_rest' => true,
        'taxonomies' => array('post_tag')
 
    );

    register_post_type( 'graduates', $args );
 
}
 
add_action( 'init', 'custom_post_type', 0 );

希望任何人都可以提供帮助！

编辑/更新： 我在页面 /毕业生上添加了短代码，这造成了错误。因此，我将URL SLUG更改为 /研究生或其他与自定义帖子类型名称不同的东西，现在可以使用！
