Laravel white screen when using Redirect Class - php

Question

I am currently getting a white screen of death when I am trying to redirect my users using the Laravel Redirect class after handling data. If I use the native php-function header("location ...") the application responds correctly and sends the user on its merry way, but using Laravel's Redirect class the site crashes with a white screen of death. I have tried both the Redirect::action and Redirect::to functions, but they are both resulting in the same irritating white screen of death. The laravel.log shows nothing...
Does anyone have any ideas?
Here is the code for the data handler controller class:
<?php
class ManagerLayoutDataController extends BaseController
{
public function route($action, $moduleID) {
if(method_exists('ManagerLayoutDataController',$action)) {
$this->$action($moduleID);
}
// Invalid action (method not found)
else {
die('Action routing error');
//return Redirect::to('/');
}
}
public function updateHeaderBg($moduleID) {
$image = Input::file('img');
$user = Auth::user();
$siteID = $user->getSiteID();
$layoutDataMessage = null;
// Validate file upload (NOT FILE CHARACTERISTICS)
if(Input::hasFile('img') && $image->isValid() && isset($siteID) && $siteID !== "") {
$res = ManagerFileUpload::uploadImage($siteID, $image);
if($res->success) {
$fileName = $res->fileName;
$dbViewModule = ViewModuleRepository::getModule($moduleID);
if($dbViewModule->type === DBViewModule::MODULE_TYPE_HEADER) {
$headerModule = new HeaderModule($dbViewModule);
$headerModule->updateBgImage($fileName);
$layoutDataMessage = new LayoutDataMessage(LayoutDataMessage::STATUS_SUCCESS,"");
}
}
else {
$layoutDataMessage = new LayoutDataMessage(LayoutDataMessage::STATUS_FAIL,$res->message);
}
}
else {
$layoutDataMessage = new LayoutDataMessage(LayoutDataMessage::STATUS_FAIL, "Bilden kunde inte laddas upp.");
}
if($layoutDataMessage != null) {
return Redirect::action('ManagerLayoutController#main')->with('message',$layoutDataMessage);
//return Redirect::to('manager/layout/');
//header('location: */manager/layout');
}
else {
return Redirect::action('ManagerLayoutController#main')->with('message',LayoutDataMessage(LayoutDataMessage::STATUS_FAIL, "Bilden kunde inte laddas upp."));
//return Redirect::to('manager/layout/');
//header('location: */manager/layout');
}
}
}
The Main Controller
<?php
class ManagerLayoutController extends BaseController
{
public function main() {
$user = Auth::user();
$siteID = $user->getSiteID();
$moduleComposition = ViewModuleCompositionRepository::getCurrentInWorkModuleComposition($siteID);
$dbViewModules = ViewModuleRepository::getModulesFromComposition($moduleComposition->id);
$viewModules = array();
foreach($dbViewModules as $dbViewModule) {
switch($dbViewModule->getType()) {
case DBViewModule::MODULE_TYPE_HEADER:
$viewModules[] = new HeaderModule($dbViewModule);
break;
case DBViewModule::MODULE_TYPE_TEXT_SECTION:
$viewModules[] = new TextSectionModule($dbViewModule);
break;
case DBViewModule::MODULE_TYPE_KEY_METRICS:
$viewModules[] = new KeyMetricsModule($dbViewModule);
break;
case DBViewModule::MODULE_TYPE_SLIDESHOW:
$viewModules[] = new SlideShowModule($dbViewModule);
break;
case DBViewModule::MODULE_TYPE_VACANCIES:
$viewModules[] = new VacanciesModule($dbViewModule);
break;
case DBViewModule::MODULE_TYPE_EMAIL_SUBSCRIPTION:
$viewModules[] = new EmailSubscriptionsModule($dbViewModule);
break;
case DBViewModule::MODULE_TYPE_CO_WORKERS:
$viewModules[] = new CoworkersModule($dbViewModule);
break;
case DBViewModule::MODULE_TYPE_NEWS_SECTION:
$viewModules[] = new NewsModule($dbViewModule);
break;
case DBViewModule::MODULE_TYPE_INSTAGRAM_FEED:
$viewModules[] = new KeyMetricsModule($dbViewModule);
break;
case DBViewModule::MODULE_TYPE_SOCIAL_MEDIA:
$viewModules[] = new KeyMetricsModule($dbViewModule);
break;
}
}
$data = array(
'siteID' => $siteID,
'viewModules' => $viewModules
);
return View::make('dashboard.pages.manager.layout_main',$data);
}
}

Answer 1

Try to add
ini_set('display_errors', 1);
It should at least tell you what is the actual error.
This is only for development mode, remove it when you go into production

Answer 2

Look if there is a "return" before the Redirect. For example:
// Unauthorized access
else {
die('Filter error');
//Redirect::to('/');
}
Here should be return Redirect::to('/');
