我正在使用woocommerce归档产品页面上的自定义商店循环。麻烦的是，我又多了一个空白页。这种分页方式对于博客很好，但在这里不行。

<?php
                $paged = ( get_query_var(\'paged\') ) ? get_query_var(\'paged\') : 1;
                $product = new WC_Product(get_the_ID());
                $params = array(\'posts_per_page\' => 12, \'post_type\' => \'product\', \'paged\' => $paged, \'tax_query\' => array(
        array(
            \'taxonomy\' => \'product_cat\',
            \'field\' => \'slug\',
            \'terms\' => array( \'free\' ),
            \'operator\' => \'NOT IN\'
        )
    ));
                $wc_query = new WP_Query($params);
                ?>
                <?php if ($wc_query->have_posts()) : ?>
                <?php while ($wc_query->have_posts()) :
                $wc_query->the_post(); ?>
                <article class="portfolio__item portfolio__item--shop">
                    <figure class="blog__image-container">
                        <?php if ( has_post_thumbnail()) {the_post_thumbnail(\'thumb-blog\' ,array("class"=>"portfolio__image post_thumbnail"));} ?>
                    </figure>
                    <h3 class="portfolio__content-title portfolio__content-title--shop"><?php the_title(); ?></h3>
                    <p class="portfolio__content-text portfolio__content-text--shop"><?php $product = new WC_Product(get_the_ID()); echo $product->get_price_html(); ?></p>
                        <div class="portfolio__content">
