Installing Symfony 2.5: blank welcome page | apc_cache_find notice - php

Question

I'm trying to install Symfony2 (I use 'Bitnami' localhost on Windows). When I open http://localhost:8080/symfony2/web/config.php I see the config page, after goint to welcome page blank page is displayed.
On http://localhost:8080/symfony2/web/app_dev.php I've turned ini_set("display_errors", "1"); and what I get is:
Notice: require_once(): 1.
h->opened_path=[C:\Bitnami\wampstack-5.4.26-0\apache2\htdocs\symfony2\app\bootstrap.php.cache]
h->filename=[C:\Bitnami\wampstack-5.4.26-0\apache2\htdocs\symfony2\app\bootstrap.php.cache]
in
C:\Bitnami\wampstack-5.4.26-0\apache2\htdocs\symfony2\web\app_dev.php
on line 27

in

on line 3
And further errors similar to these.
I saw this: APC (Alternate PHP Cache) Throwing Lots of PHP Notices
But I'm not sure what should I do with Enable internal debugging in APC [no] :no
I'm stuck. What should I do next?

As far as I know there is currently no APC module for PHP5.5 on Windows so you have to use another cache module. You did not write which Xampp version you are using, but I suppose a more recent one.
Please try to use APCu and enable it in php.ini
extension = "C:\xampp\php\ext\php_apcu.dll"
apc.enabled = 1
It worked for me on Windows.
Also, Zend released in PHP5.5 their new OPCache as an alternative to APC. More info can be found here enter link description here. Could be also useful but I never tried that one.
