exception 'Zend_Controller_Action_Exception' with message 'Action "index" does not exist and was not trapped in __call()?

Anyone know what this error means? after googling I found a bunch of sites that appear to have the same error? thanks

exception 'Zend_Controller_Action_Exception' with message 'Action "index" does not exist and was not trapped in __call()' in /usr/local/zend/apache2/htdocs/pintsy/lib/Zend/Controller/Action.php:485

It means there's no indexAction method in your controller class.

Your controller was instantiated and, based on the URL, Magento determined the action was "index". This is the default action. For example, if you have a URL like this

http://example.com/products/

is usually (Zend is used differently all over the place) the same as a URL like this

http://example.com/products/index

That is, they would both instantiate a ProductController and with an action of index.

public function indexAction(){...}

So, your controller is missing a method named indexAction. What happens next is, the request is sent to PHP magic __call method. If this method exists on a class, calls to non-existent methods go there. The Zend Exception is telling you that, in addition to there being no method for indexAction, there was nothing in __call about indexAction either.

If you got the same error in apache log means, it might be because of invalid path for the css or javascript or image files
