Ion Auth&；Codeigniter:新用户登录时循环重定向

我是Codeigniter的常客，现在我不得不开始查看库中的登录/忘记密码，所以我决定使用Ion Auth。

我设置了这个-工作正常，尝试了已经设置的管理员帐户，它很好。

现在，当我以管理员身份登录并创建新用户时，数据会添加到数据库中，页面会从"创建用户"重定向到欢迎页面。但是，如果我注销并使用这些新的详细信息登录，页面就会变为空白，重新加载栏就会变得疯狂！url栏看起来像是进入了欢迎页面，如果这是有意义的，但没有加载任何内容。

我还检查了firebug上的控制台和php日志错误，但什么都没有。

我已经检查了我的数据库，当添加用户时，密码已经被散列，但在salt列中，它被归类为NULL，而已经设置的默认帐户有散列代码？-这和它有关系吗？

EDIT：我现在已经修改了代码，但当它没有被触摸时，这仍然不起作用，所以代码中的编辑只是删除表，而在auth控制器中，函数是login、create_user和logout。

当admin@admin.com用户登录后，只需其他"新"帐户即可加载页面。。

谢谢！

欢迎页面控制器

class Welcome extends CI_Controller {
    function __construct() {
        parent::__construct();
        $this->load->library('ion_auth');
        $this->load->library('session');
        $this->load->library('form_validation');
        $this->load->helper('url');
    }

        public function index() {
        if (!$this->ion_auth->logged_in()) {
            redirect('auth/login', 'refresh');
        }elseif (!$this->ion_auth->is_admin()) {
            redirect('/', 'refresh');
        }else{
            $this->data['message'] = (validation_errors()) ? validation_errors() : $this->session->flashdata('message');
            $this->_render_page('auth/welcome', $this->data);
        }
    }
}

解决方案：这是谷歌Chrome的一个错误，我不得不更新系统和brwser。同样为了存储SALT，我在我的_auth配置文件中更改了一些设置
