Php codeigniter中的分页URL问题

我在我的站点中添加了分页，它似乎可以很好地显示每页的结果，但在单击“下一页”后，显示错误为“未找到页面” 基本url也是正确的。在模型中，还有一个过滤器代码。单击第二页后，错误显示为404页未找到

启动控制器代码：

    $config['uri_segment'] = 3;
    $config['total_rows'] = $total_rows;
    $config['per_page'] = 8;
    $per_page = $config['per_page'];
    $offset = $config['per_page'];
    $config['num_links'] = 3;
    $config['full_tag_open'] = '<ul class="pagination ">';
    $config['full_tag_close'] = '</ul>';
