How to track jos-Error in Joomla 2.5?

Question

I made one of my menu items only for Guests (not logged in users). ANd If user logs in, it disappears from menu. It works fine...

But I noticed that when I put the link to the Guest menu item in browser, when I'm lnot ogged in , it shows very disgusting jos-Error: You are not authorised to view this resource.

I want to find a way to track such errors and redirect to custom 404 page or some other page.

Please, assist me in this issue.

Thanks

The string You are not authorised to view this resource located in JERROR_ALERTNOAUTHOR language string and fire in includes/application.php function:

public function authorise($itemid)
    {
        $menus  = $this->getMenu();
        $user   = JFactory::getUser();

        if (!$menus->authorise($itemid))
        {
            if ($user->get('id') == 0)
            {
                // Redirect to login
                $uri        = JFactory::getURI();
                $return     = (string)$uri;

                $this->setUserState('users.login.form.data', array( 'return' => $return ) );

                $url    = 'index.php?option=com_users&view=login';
                $url    = JRoute::_($url, false);

                $this->redirect($url, JText::_('JGLOBAL_YOU_MUST_LOGIN_FIRST'));
            }
            else {
                JError::raiseError(403, JText::_('JERROR_ALERTNOAUTHOR'));
            }
        }
    }

You could alter this function and add redirection or change the text string with your desired message.

Redirect could be done with redirect() method.

An example of redirect syntax:

$app = JFactory::getApplication();
$app->redirect(JRoute::_(JURI::root().'index.php'));

Please make sure that you won't alter application.php without creating an override system plugin.

Hope this helps
