Symfony2.3生产页面空白500

Question

after working with my project on dev mod, i found some problems with prod on OVH. it shows me a blank page ! i try to follow the issue on app.php and i found that the problem persist with the execution of $response = $kernel->handle($request); and it don't logging on prod.

so when i change the row on app.php : $kernel = new AppKernel('prod', false); with $kernel = new AppKernel('dev', false); it works well !!!

here's my app.php

<?php

 */
umask(0000);
require_once __DIR__ . '/../app/bootstrap.php.cache';
require_once __DIR__ . '/../app/AppKernel.php';

//use Symfony\Component\HttpFoundation\Request;

// if you want to use the SonataPageBundle with multisite
// using different relative paths, you must change the request
// object to use the SiteRequest
use Sonata\PageBundle\Request\SiteRequest as Request;

$request = Request::createFromGlobals();

$kernel = new AppKernel('prod', false);

$response = $kernel->handle($request);
$response->send();

$kernel->terminate($request, $response);

EDIT : in dev and prod local mode test it works well with

 php app/console cache:clear --env=prod --no-debug 
php app/console assets:install web_directory 
php app/console assetic:dump web_directory

should i add or install php5 on my project ?

EDIT : my project contains : sonata-project, fosUserBundle,etc...

EDIT

the problem was on config_prod.xml

doctrine:
    orm:
        entity_managers:
            default:
                metadata_cache_driver: apc
                query_cache_driver:    apc
                result_cache_driver:   apc

intil now after it return an error 500 ! why ? because of apc was not enabled ! so my question how to enable apc on OVH pro !

Answer 1

Go to web/config.php and comment ot the following lines:

if (!in_array(@$_SERVER['REMOTE_ADDR'], array(
    '127.0.0.1',
    '::1',
))) {
    header('HTTP/1.0 403 Forbidden');
    exit('This script is only accessible from localhost.');
}

That will enable the config.php to be called from "extern". Don't forget to remove the comments after you've checked everything.

If you have console access on the production server, enter the root directory of your project and call php app/check.php to run the checks on the console.
