ERR_TOO_MANY_REDIRECTS in index.php YII -

i have close access index.php main page, modified sitecontroller.php following code:

public function accessrules() {   return array(     // allow users perform 'index' , 'view' actions *     array('allow',       'actions' => array('index','view'),       'users' => array('admin'),     ),     // allow authenticated user perform 'create' , 'update' actions @     array('allow',       'actions' => array('create','update'),       'users' => array('admin'),     ),     // allow admin user perform 'admin' , 'delete' actions     array('allow',       'actions' => array('admin','delete'),       'users' => array('admin'),     ),     // deny users     array('deny',       'users' => array('*'),     ),   ); } 

because have give access admin. after manipulations saw redirect working, , url becomes index.php/site/login, instead of login/pass form got err_too_many_redirects. hope understand me)

i had same problem , solution add "error" action rules, allowing users access it. got because after doing update generated error , error action couldn't accessed.
