Could you paste your kernel file? Looks like the frameworkBundle ain't instantiated. In the standard edition config_dev extends config.yml, so the framework config should be in config.yml.

@bamarni the FrameworkBundle config is also in config_dev.yml to activate the profiler. But missing the FrameworkBundle is indeed the most likely reason.

@bamarni, @stof: did you need something from me? As I said before I just download the release from www.symfony.com, uncompress and try I didn't touch nothing at code level so if there's any mistake is presented here at git or in the .tgz file.

@paquitodev: compare what you have with https://github.com/symfony/symfony-standard/tree/v2.0.14, especially app/AppKernel.php.

Is the same file means the code here at Github is the same as my AppKernel.php code

What do you have in your vendor directory? If you have nothing, what did php bin/vendors install output?

This: a
assetic
bundles
doctrine
doctrine-common
doctrine-dbal
metadata
monolog
swiftmailer
symfony
twig
twig-extensions
As I said and repeat once more time, I just download the copy from www.symfony.com and uncompress in my local server. The files I have are those one that are presented in the .tgz file so if there is any error maybe come from there. But also I do a php app/vendors --reinstall and the error still

There are several tgz on symfony.com one with vendors and another without. Hence my question. Is there any error displayed for any bundle when your run php bin/vendors --reinstall or with any other option?
Additionally, what do you have in the vendor/bundles directory? Sometimes, github fails to respond correctly and the clone fails.

Yes I knew that part but I get the tgz with vendors the first one that download when you click in the big download button at home page ;) and no I not get any errors during vendors reinstall process

See the output of php bin/vendors install --reinstall

[root@reynierpm-devpc bin]# ./vendors install --reinstall

So no errors there too :(

you don't have to run this command if you downloaded the full package as you said, could you somehow show us the whole code you have (witouth vendors) ?

Which code you need?

your app directory, or the whole code witouth vendors

And how? Send you by email? How can I attach a file here?

And how? Send you by email? How can I attach a file here?

Aren't we on github? :)

So .... how to achieve this "could you somehow show us the whole code you have (witouth vendors)"??

Ok, it's confirmed the problem is with PHP 5.4.x because I downgrade to PHP 5.3.13 and now Symfony 2.0.14 works fine!

@paquitodev : you could achieve this by creating a github repository, if you know what that is.
@bamarni: but I doubt it would be helpful, because @paquitodev said he did not modify anything at all. And confirmed the compatibility issue.
Fedora 17 will be out tomorrow, and it includes php 5.4, as you can see here : https://fedoraproject.org/wiki/Releases/17/FeatureList
I am sending this message from a Fedora 16 machine, which I intend to upgrade tomorrow. If I can, I'll see if I reproduce this bug tomorrow.

looks weird, did anybody had this issue with php 5.4? I was using symfony with a 5.4 RC a few months ago and didn't have this issue.

@greg0ire : ok keep us updated ;)

Actually, I'm having problems to upgrade : https://bugzilla.redhat.com/show_bug.cgi?id=826272 on my main machine. I won't be able to test this evening. Sorry...

I solved my problems and was unable to reproduce this bug on a Fedora 17 with php 5.4.3

I have the exact same problems (including the message) in the same circumstances, but i run PHP 5.4.3 on ArchLinux. check.php is also perfect.

I can confirm that after update from Fedora 16 to Fedora 17 which come with PHP 5.4.3 all my problems dissapear magically so Symfony it's working now under PHP 5.4.3. Don't know if close the issue or leave open for others like @leokolin who have the same problem

I´m back to work today. Still trying to solve the problem but i have no clue at all.
Doesn't look like a permission issue, tried change the umask() lines, always cleared the cache folders (there are files being created there, so it is not a permission, at least on the cache side). Even tried a 777 from on all the files (including all the parent folders).
Can a apache configuration be the source to the problem?
@paquitodev I see that the problem ceased when you changed the version of the SO, but we didn't find the source of the problem...

@leokolln: Maybe you could try to do step-by-step debugging with XDebug to find the source of the problem.

@leokolln Yes my problem ceased after I upgrade from Fedora 16 to Fedora 17 maybe REMI repos miss something at PHP 5.4.3 compilation or I don't know. I was experimenting this problem also with CodeIgniter and some others apps I have in my dev server so the problem is PHP and not the apps. What's the poblem? Don't know really :(

--> config_dev.yml
framework:
router: { resource: "%kernel.root_dir%/config/routing_dev.yml" }
profiler: { only_exceptions: false }

-->--> routing_dev.yml

</route>

<route id="_configurator_final" pattern="/final">
    <default key="_controller">SensioDistributionBundle:Configurator:final</default>
</route>

reading the method at YamlFileLoader.php line 272:
if (!$this->container->hasExtension($namespace)) { ... }

The method is one of those ones:
--> ContainerBuilder.php line 98
public function hasExtension($name)
{
return isset($this->extensions[$name]) || isset($this->extensionsByNs[$name]);
}

or

--> Environment.php line 604
public function hasExtension($name)
{
return isset($this->extensions[$name]);
}

So...
Looking at this i can infer that there is no extension (or not registered) able to load a .xml file.

But how can this sometimes work, some not?

Forget the part about the .xml. I´m still new to Symfony.

Trying to use the app.php/demo returns a code 500 error. Using xdebug i found this: 'There is no extension able to load the configuration for "monolog" (in /srv/http/Symfony/app/config/config_prod.yml). Looked for namespace "monolog", found none'

FOUND IT!
The problem is with the APC PHP extension. I disabled it and the problem is gone.

So, this is the problem, i will still try to discover what is the problem with APC.

Looks like APC is not very stable with PHP5, specially in last versions of it. Do not use it!

Closing this issue. Support should be done on the Symfony mailing-list instead.

For the record, there are some known bugs with APC and PHP 5.4. We have made some workaround for some of them.
