zend framework - Uncaught exception 'Zend_Controller_Dispatcher_Exception' -

I get the following error on the Zend Framework:

 Fatal Error: Ignored Exceptions 'Zend_Controller_Dispatcher_Exception' In the message 'Invalid Controller Specified (Error)' in F: \ wamp \ www \ helloworld \ library \ Zend \ Controller \ Dispatcher \ Standard.php: 245 Stack Trace: # 0 F: \ wamp \ www \ helloworld \ library \ Zend \ Controller \ Front.php (946): Zend_Controller_Dispatcher_Standard-> Send (Object (Zend_Controller_Request_Http), Object (Zend_Controller_Response_Http) # 1F: \ wamp \ www \ helloworld \ library \ Zend \ Controller \ Front.php (212) : Zend_Controller_Front-> Sending ( ) # 2 F: \ wamp \ www \ helloworld \ web_root \ index.php (10): Zend_Controller_Front :: Run ('../ application / ...') # 3 {main} Throw in F: 
 
 
 
 
 
 
 
 
 
 
 
 
 
 Write in the index.php file 
 
  $ frontControl  
 
 Alternatively you can write the following line; In the [Production] section of the Application.ini file: 
 
  resources.frontController.params.useDefaultControllerAlways = 1
