laravel 4直接登录后注销？

Question

我尝试通过电子邮件和密码登录 auth ::尝试成功登录但是当登录后重定向到链接它自己注销，在localhost上一切都很好但是当我在主机上传我的项目时出现了这个问题

登录功能

public function login(){

            $validator=Validator::make(Input::all(),array(

                    'email'     =>  'email|required',

                    'password'  =>  'required'

                ));



            if($validator->fails()){

                $messages = $validator->messages();

                $msg='';

                foreach ($messages->all() as $message)

                {

                    $msg .= "<li>".$message."</li><br />";

                }

                return $msg;

            }

            else{

                $email = Input::get('email');

                $password = Input::get('password');

                $user=Auth::attempt(array(

                    'email' =>  $email,

                    'password'  =>  $password,

                    'activated' =>  1

                ),true);
                //die(Auth::user()->rule);
                if($user){
                    //Auth::login($user);
                    //die('1111111111');
                    return 1;

                }

                else{

                    return "يوجد خطأ فى البريد الإلكترونى أو كلمة المرور";

                }
                //die('11111111111111111');
            }

        }
