有时你需要写新的动作。要解决类别库问题，需要添加和删除一些操作。您可以将此代码作为自定义插件进行尝试。也许这可以解决你的问题。代码完全删除/category/ 基础

将此代码添加到主题functions.php 或者使用此代码创建自定义插件。

如果您使用的是Apache，请在.htaccess 在WordPress安装的根目录中。这将自动为您执行重定向。

注：更换http://www.example.com 使用您的网站URL。

RewriteRule ^category/(.+)$ http://www.example.com/$1 [R=301,L]

是否尝试筛选$wp\\u查询对象？您可以使用此代码段直接在DB中搜索类别slug：

function pm_detect_term_slugs($query) {
    global $wpdb;

    // Do not run when Elementor is opened
    if((!empty($_REQUEST[\'action\']) && strpos($_REQUEST[\'action\'], \'elementor\') !== false) || isset($_REQUEST[\'elementor-preview\'])) {
        return $query;
    }

    // 1. Get the slug
    if(!empty($query[\'pagename\'])) {
        $slug = $query[\'pagename\'];
    } else if(!empty($query[\'name\'])) {
        $slug = $query[\'name\'];
    } else if(!empty($query[\'attachment\'])) {
        $slug = $query[\'attachment\'];
    }

    if(!empty($slug)) {
        $slug = basename($slug);

        // 2. Check if the slug is assigned to any post item
        $sql_query = "SELECT t.slug, t.term_id, tt.taxonomy FROM $wpdb->terms AS t INNER JOIN $wpdb->term_taxonomy AS tt ON(tt.term_id = tt.term_id) WHERE 1=1 AND slug = %s";
        $term = $wpdb->get_row($wpdb->prepare($sql_query, array($slug)));

        // 3. Filter the query if any term was found
        if(!empty($term->taxonomy)) {
            $page = (!empty($query[\'paged\'])) ? $query[\'paged\'] : 1;

            $new_query = array(
                \'term\' => $term->slug,
                \'taxonomy\' => $term->taxonomy,
                \'paged\' => $page
            );

            // 4. Disable canonical redirect
            remove_action(\'template_redirect\', \'wp_old_slug_redirect\');
            remove_action(\'template_redirect\', \'redirect_canonical\');
            add_filter(\'wpml_is_redirected\', \'__return_false\', 99, 2);
            add_filter(\'pll_check_canonical_url\', \'__return_false\', 99, 2);

            return $new_query;
        }
    }
    return $query;
}
add_filter(\'request\', \'pm_detect_term_slugs\', 9999);
