In your UsersController, try adding the following lines BEFORE you
execute $this->Cookie->write():
debug(Configure::read('Security.salt');
debug($this->Cookie->key);
The first line displays the default key that the CookieComponent uses
(usually defined in app/config/core.php), but the second line is the
actual value that Security::cipher() actually tries to use.
If both debug values are blank, check your code for places where
Configure::write(Security.salt, ...) is being executed. If the first
debug value is not blank, but the second one is, check your
AppController and UsersController if you are overriding the default
value for $this->Cookie->key (either by using the
var $components = array('Cookie' => array(...));
syntax, or by
$this->Cookie->key = ...;
