I am having major issues here, I had thought that separating the login
processing and the logout functions from the index page where the
actual login form is rendered would solve the issues im having but I
was mistaken. The issue still remains, I select logout and the
browser hourglasses and times out.
Is there some internal MVC zend log that I can take a look at? I have
taken a look at the apache logs but nothing happens. Its as if the
request is stuck in the framework. Im not sure it will help, but this
is my logout function and my index function inside the index
controller:
class IndexController extends Zend_Controller_Action
{
public function indexAction()
{
$config = Zend_Registry::get('config');
$this->view->title = $config->english->login->title;
$this->view->baseurl = $config->production->hosturl;
$this->view->shead = $config->english->login->subheader;
$this->view->form = $this->getLoginForm();
$this->_helper->layout->disableLayout();
}
And logout function:
public function logoutAction()
{
Zend_Auth::getInstance()->clearIdentity();
return $this->_helper->redirector('index');
}
