Error: Dispatcher has detected a cyclic routing causing stability problems

look guys!

$di->set('dispatcher', function() use ($di) {
$eventsManager = $di->getShared('eventsManager');
$eventsManager->attach('dispatch:beforeDispatch',function (Event $event, Dispatcher $dispatcher){
    $plugin = new Plugin();
    $security = new SecurityPlugin();
    $auth = $plugin->session->get('auth');
    if (!$auth){
        $role = 'Guests';
    } else {
        $role = 'Users';
    }
    $controller = $dispatcher->getControllerName();
    $action = $dispatcher->getActionName();

    $acl = $security->getAcl();
    echo (!$acl->isRole($dispatcher->getControllerName())) ? "true<br>" : "false";
    //$allowed = $acl->isAllowed($role, $controller, $action);
    if (!$acl->isRole($dispatcher->getControllerName())) {
        $dispatcher->forward(array(
            'controller' => 'errors',
            'action'     => 'show404'
        ));
        //header("index.php?_url=errors/show404");
        return false;
    }
});
$eventsManager->attach('dispatch:beforeException',function(Event $event, Dispatcher $dispatcher,$exception){
    switch($exception->getCode()){
        case PhDispatcher::EXCEPTION_HANDLER_NOT_FOUND:
        case PhDispatcher::EXCEPTION_ACTION_NOT_FOUND:
            $dispatcher->forward(array(

my problem in this code and that is showing this message, and I've tried everything I have no more idea someone could help me? My ACL is this way:

 public function getAcl(){
    //throw new \Exception("something");
    if (!isset($this->persistent->acl)) {
        $acl = new AclList();
        $acl->setDefaultAction(Acl::DENY);
        $roles = array(
            'users'  => new Role('Users'),
            'guests' => new Role('Guests')
        );
        foreach ($roles as $role) {
            $acl->addRole($role);
        }
        //Private area resources
        /*$privateResources = array(
            'companies'    => array('index', 'search', 'new', 'edit', 'save', 'create', 'delete'),

        );
        foreach ($privateResources as $resource => $actions) {
            $acl->addResource(new Resource($resource), $actions);
        }*/
