Phalcon 3 and PHP 7 breaking the existing site - php

Question

My problem started right after I upgraded PHP to Version 7 and Phalcon to Version 3.
Problem
I m getting blank page, no error messages (Error is turned on), no `500 Internal server' error in console. The site used to work flawlessly before.
I have following controller IndexController.php
<?php
namespace RealEstate\Property\Controllers;
use \Phalcon\Mvc\Controller;
use \Phalcon\Mvc\View;
use RealEstate\Common\Models as CommonModels;
class IndexController extends Controller
{
public function initialize(){
//Code here
}
public function indexAction(){
$this->view->setRenderLevel(View::LEVEL_ACTION_VIEW);
$this->view->setVar("total_properties", $this->utils->getTotalProperties());
$this->view->pick("index");
echo "HELLO WORLD";
}
}
The index action doesnot render anything, but yes HELLO WORLD is printed, so there seems there is no errors in code above that line.
My bootstrap index.php
<?php
namespace RealEstate;
use \Phalcon\Mvc\Application;
use \Phalcon\DI\FactoryDefault;
use \Phalcon\Loader;
use \Phalcon\Mvc\Router;
use \Phalcon\Mvc\View;

Have followed This Link as well, but with not much help.
UPDATE
No errors on Server's error log
Thanks

Answer 1

I think I solved this issue. The issue was in Module.php, the issue was in method
public function registerServices($di)
{
try{
//Registering the view component
$di->set('view', function() {
$view = new View();
$view->setViewsDir('../apps/modules/'.$this->module_name.'/views/');
return $view;
});
}catch(\Phalcon\Exception $e){
echo get_class($e), ": ", $e->getMessage(), "\n";
echo " File=", $e->getFile(), "\n";
echo " Line=", $e->getLine(), "\n";
echo $e->getTraceAsString();
}
}
Where, $module_name is a property defined in class.
In above code $this->module_name was undefined. so I changed above method to -
public function registerServices($di)
{
$module = $this->module_name;
try{
//Registering the view component
$di->set('view', function() use($module) {
$view = new View();
$view->setViewsDir('../apps/modules/'.$module.'/views/');
return $view;
});
}catch(\Phalcon\Exception $e){
echo get_class($e), ": ", $e->getMessage(), "\n";
echo " File=", $e->getFile(), "\n";
echo " Line=", $e->getLine(), "\n";
echo $e->getTraceAsString();
}
}
I wondered why it was working in previous version of Phalcon
