更改永久链接后，自定义页面不起作用

Question

我有带有Slug博客的页面名称博客。我已将永久链接从普通名称更改为职位名称，此页面现在无法正常工作，但是更改永久链接后的所有其他页面都可以正常工作。在更改永久链接之前，页面工作正常，如果我将其恢复为普通的永久链接，则页面将再次开始工作。我的代码是

        <?php
        /*
            Template Name: Blog
        */
        ?>

        <?php get_header(); ?>


        <?php

        ?>

        <div class="wrap">


            <?php

            $getCurrentPage = get_query_var('paged', 1);


            $aboutPosts = new WP_Query(array(
                'posts_per_page' => '12',
                'post_type' => array(
                    'custom_2nd',
                    'custom',
                    'post',
                    'custom_3rd'
                ),
                'paged' => $getCurrentPage
            ));



            ?>
            <section class="">
                <?php
                if ( $aboutPosts->have_posts() ) :

                    ?>



                    <div class="columns is-multiline  is-variable is-4 is-centered">

                            $aboutPosts->the_post();

                            /*
