i'm doing app using laravel, , i'm doing login system. in login don't have problem, in logout browser gets error

whoops, looks went wrong. 

my login function

public function postsignin() {     if (auth::attempt(array('email'=>input::get('email'), 'password'=>input::get('password')))) {         return redirect::to('users/dashboard')->with('message', 'you logged in!');     } else {         return redirect::to('users/login')             ->with('message', 'your username/password combination incorrect')             ->withinput();     } } 

my logout function

public function getlogout() {     auth::logout();     return redirect::to('users/login')->with('message', 'your logged out!'); } 

if remove line auth::logout(); page redirected can't use auth::check() verify if user logged in.

the error that

see: http://laravel.com/docs/upgrade#upgrade-4.1.26

laravel requires "nullable remember_token of varchar(100), text, or equivalent users table."
