Pagination crashes on pages, how to fix it?

Question

WordPress

Pagination crashes on pages (custom post type) due to WooCommerce installation.

If you do not install WooCommerce, everything is ok, as soon as it is installed, it displays a 404 error when clicking on the links.

Page with pagination: https://skazkamini.ru/reviews/

Page code:

<?php 

/*
Template Name: Reviews Template
*/

get_header();

?>


<section class="section-reviews section-page">
  <div class="container">
    <h2 class="section__title">Отзывы о нашей работе</h2>
    <div class="news">

      <?php 

        $paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
        $reviews_args = array(
          'paged'          => $paged,
          'post_type'     => 'reviews',
          'posts_per_page' => '1',
          'order'         => 'DESC'
        );

          $reviews_query = new wp_Query($reviews_args); ?>

          <?php echo $paged ?>

          <?php if($reviews_query -> have_posts()) { while ($reviews_query -> have_posts()) : $reviews_query-> the_post();?>

            <div class="news__item card-box dashed">

Answer 1

there should not be identical slugs on the site so that there are no conflicts, most likely the page is loaded via the /reviews link because it is more priority than the archive, and at /reviews/page/2 it is already a review archive template, but due to the fact that there are less than two reviews page (less than 10), then the second page does not exist, and gives 404.
You can check if you change the page slug or change rewrite in the post_type settings of the reviews, then save the permalinks. If the problem was in the conflict of slugs, then it will start working
