Symfony2 always displays blank page in production

The application works in dev and test and a custom environment, but it does not work in production mode. I have tried all solutions I could find online, but couldn't solve the problem. The project is not so small and it stopped worked recently.

-Bundles are loaded fine in AppKernel

-Routing debug display all routes fine in production

-In app.php: $kernel = new AppKernel('prod', true);

-I have cleared cache and warmed it up. If I load without cache, it generated the prod cache fine.

-If I try to access any route, even an non-existing one, I get a blank page, so it looks like the routes are not being checked.

-No logs are written for production environment, also apache does not log anything. (logs work in other environments by monolog.)

I am using Symfony 2.4.5

Someone can help me here?

What does the error.log say? – Bartek
No logs are created for production environment, not even apache shows any logs. – tomazahlin
Did you modify the original app.php file? – Bartek
I have not modified the app.php in any way, it is the same as original. (only tried changing debug to true/false) – tomazahlin
If there's no logs it's hard to say what might went wrong. Maybe APC is the problem? Have you tried to clear APC or restart apache? – Bartek

This actually points to a FATAL php error. But, as expected, you production server has display_error = Off.

It is hover weird that apache does not produce any errors in log file :-/ Inspect your web directory - maybe you'll find the php_error file there containing some details?

EDIT:

Just remembered, thanks to the comments mentioning the APC. Similar thing used to happen to me beacause I had APC enabled in app but my dev box did not have APC installed/enabled

did you give full permission to app/log and app/cache folders?

sudo chmod -R 777 app/cache app/logs
