zend_application showing blank page

Question

Hi,

I'm using Zend_Application to bootstrap my app.

class Bootstrap extends Zend_Application_Bootstrap_Bootstrap

{ public static $frontController = null; public static $registry = null;

protected function _initEnvironment()
{
    ini_set('display_errors', true);
    //date_default_timezone_set('Europe/London');
}

protected function _initRegistry()
{
    self::$registry = new Zend_Registry(array(), ArrayObject::ARRAY_AS_PROPS);
    Zend_Registry::setInstance(self::$registry);
}

protected function _initConfiguration()
{
    $config = new Zend_Config_Ini(
        BASE_PATH . '/data/server/settings.ini',
        APPLICATION_ENV
    );
    self::$registry->configuration = $config;
}
protected function _initLogging() {
     $config = self::$registry->configuration;
     $logger = new Zend_Log(new Zend_Log_Writer_Stream($config->logging->file)); 
     Zend_Registry::set('logger', $logger);
}
protected function _initFrontController()
{
    self::$frontController = Zend_Controller_Front::getInstance();
    self::$frontController->throwExceptions(true);
    self::$frontController->returnResponse(true);
    self::$frontController->setControllerDirectory(
        APPLICATION_PATH .'/controllers'
    );
    self::$frontController->setParam('registry', self::$registry);
    return self::$frontController;
}
protected function _initView()
{
    $config = self::$registry->configuration;
    $view = new Zend_View;
    $viewRenderer = new Zend_Controller_Action_Helper_ViewRenderer($view);
    Zend_Controller_Action_HelperBroker::addHelper($viewRenderer);
    Zend_Layout::startMvc(
         array(
            'layoutPath' => APPLICATION_PATH . "/layouts/scripts",
            'layout' => "layout"
        )
        );
  return $view;
}
protected function _initDatabase()
{
    $config = self::$registry->configuration;
    $params = array('host'  => $config->database->hostname,
            'username' => $config->database->username, 
            'password' => $config->database->password, 
            'dbname'    => $config->database->database);
            $db = Zend_Db::factory($config->database->type, $params); 
    Zend_Registry::set('db', $db);
}
protected function _initPlaceholders() {
    $view = $this->getResource('View');
    $view->doctype('XHTML1_STRICT');
    $view->headTitle('Greplin')
         ->setSeparator(' / ');
    $view->headLink()->prependStylesheet('/src/css/header.css');
    $view->headScript()->prependFile('/js/site.js');
    return $view;
}

}

When I run the app I get a blank page. Filenames / paths are intact.

If I add die() to the bottom of my layout.phtml, I get the page.

Something is resetting the headers and sending a blank page. My error reporting is on and I get unrelated errors.

What could this be?!

Thanks!

It sounds like an error in your code is causing requests to be forwarded to your error controller. Make sure the following is set for your environment in application.conf:

phpSettings.display_startup_errors = 1
phpSettings.display_errors = 1

Also check ErrorController.php to make sure something outputs when there's an error.

Of course, you should always check your server logs as well.
