Laravel验证用户突然无法正常工作

突然我的登录不起作用，无法验证我的用户，但如果我注册一个新用户登录authomatic我只是改变了路由，但如果我回滚仍然无法使其工作 .

routes.php文件：

//pagina inicial
Route::get('/', 'PublicController@welcome');

//hilos
Route::get('/seccion/{subboaName}', 'ThreadController@index');
Route::post('/seccion/{subboaName}', 'ThreadController@store');
Route::get('/thread/{img}', 'ThreadController@mostrarImagen');

//Invitaciones
Route::get('/administrar/invitaciones', 'invitacionController@index');
Route::get('/administrar/invitacion/{id}', 'invitacionController@mostrarInvitacion');
Route::delete('/administrar/invitacion/{id}', 'invitacionController@eliminarInvitacion');
Route::post('/administrar/invitacion', 'invitacionController@invitacion');

//Secciones
Route::get('/administrar/secciones', 'BoardController@index');
Route::get('/administrar/seccion/{id}', 'BoardController@mostrarSeccion');
Route::delete('/administrar/seccion/{id}', 'BoardController@eliminarSeccion');
Route::post('/administrar/secciones', 'BoardController@seccion');

//Subsecciones
Route::get('/administrar/subsecciones', 'SubboardController@index');
Route::get('/administrar/subseccion/{id}', 'SubboardController@mostrarSubseccion');
Route::delete('/administrar/subseccion/{id}', 'SubboardController@eliminarSubseccion');
Route::post('/administrar/subsecciones', 'SubboardController@subseccion');

//usuarios
Route::auth();
