Php 第2页未加载页面navi wordpress

我已经设置了一个查询，每天查询每页80篇文章，但它没有为我加载第2页。它总是说404错误。我真的不知道我哪里出错了。这是代码

  <div class="mainvideoscon">
  <div class="videosallcenter">

            <?php
    $paged = get_query_var('paged') ? get_query_var('paged') : 1;
    $args = array(
        'post_type' => array('post','video', 'featured', 'spotlight'),
        'paged' => $paged
   );
    $wp_query = new WP_Query($args);
    if (have_posts()) : while ($wp_query->have_posts()) : $wp_query->the_post();
    if ($current_date != get_the_date('d-m-Y')) {
        echo '<div class="datetitlecon"><header class="datetitleh"><span class="datetitlehb"><i class="fa fa-clock-o"></i>&nbsp;' . get_the_date('l ') . '</span>';
        echo '' . get_the_date('dS M Y') . '</header></div>';
        $current_date = get_the_date('d-m-Y');

提前感谢您的帮助

尝试用此变量替换$arg变量

$args = array (
    'post_type'              => array('post','video', 'featured', 'spotlight'),,
    'post_status'            => 'publish',
    'pagination'             => true,
    'posts_per_page'         => '80',
);
