zend newbie - Message: Action "xxxxxxxxxxxxx" does not exist and was not trapped in __call()

Question

I was doing some clean up on a test project in Zend, and now main index page works, but every active link gives this error.

An error occurred
Page not found
Exception information:

Message: Action "xxxxx" does not exist and was not trapped in __call()
Stack trace:

#0 C:\xampp\php\PEAR\Zend\Controller\Action.php(515): Zend_Controller_Action->__call('authentificatio...', Array)

Request Parameters:

array (
  'controller' => 'index',
  'action' => 'xxxxxxx',
  'module' => 'default',
)  

bootstrap looks like this:

protected function _initAutoload()
{
    $modeLoader = new Zend_Application_Module_AutoLoader(array
        ('namespace'=>'',
        'basePath'=>APPLICATION_PATH ));
     //echo(APPLICATION_PATH);  
    return $modeLoader;
}
