routing - Symfony 2 - An error occurred while loading the web debug toolbar (404: Not Found)

Question

Since the update to symfony 2.2, the web debug toolbar is no longer loaded in app_dev.php.

I get the following error:

An error occurred while loading the web debug toolbar (404: Not Found).
Do you want to open the profiler?

In the prod.log I get the following:

request.ERROR: Uncaught PHP Exception SymfonyComponentHttpKernelExceptionNotFoundHttpException: "No route found for "GET /_profiler/84fb75cc3ffd5435474ebe4250e01fac2cdf49c1"" at /httpdocs/project/app/cache/prod/classes.php line 3597 [] []

request.ERROR: Uncaught PHP Exception SymfonyComponentHttpKernelExceptionNotFoundHttpException: "No route found for "GET /_wdt/452d5b4aa2dd9388285fa1c286d5c54218029c71"" at /httpdocs/priject/app/cache/prod/classes.php line 3597 [] []

I have cleared the cache several times :)

Interesting is the fact that in /app_dev.php all links on the page no longer links to /app_dev.php.

including the profile (/_profiler/5fdc27cb82c4e9e426b3ab27377deb0b760fdca2) when i modify the url manually, and add the app_dev.php to the url, the profiler loads correctly.

routing_dev.yml:

_assetic:
    resource: .
    type:     assetic

_wdt:
    resource: "@WebProfilerBundle/Resources/config/routing/wdt.xml"
    prefix:   /_wdt

_profiler:
    resource: "@WebProfilerBundle/Resources/config/routing/profiler.xml"
    prefix:   /_profiler

_configurator:
    resource: "@SensioDistributionBundle/Resources/config/routing/webconfigurator.xml"
    prefix:   /_configurator

_main:
    resource: routing.yml

I would be grateful for any help.

UPDATE I: config_dev.yml

imports:
    - { resource: config.yml }

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

web_profiler:
    toolbar: true
    intercept_redirects: false

monolog:
    handlers:
        main:
            type:  stream
            path:  %kernel.logs_dir%/%kernel.environment%.log
            level: debug
        firephp:
            type:  firephp
            level: info
        chromephp:
            type:  chromephp
            level: info

assetic:
    use_controller: true

UPDATE II: AppKernel.php

use SymfonyComponentHttpKernelKernel;
use SymfonyComponentConfigLoaderLoaderInterface;

class AppKernel extends Kernel
{
    public function registerBundles()
    {
        $bundles = array(
            new SymfonyBundleFrameworkBundleFrameworkBundle(),
            new SymfonyBundleSecurityBundleSecurityBundle(),
            new SymfonyBundleTwigBundleTwigBundle(),
            new SymfonyBundleMonologBundleMonologBundle(),
            new SymfonyBundleSwiftmailerBundleSwiftmailerBundle(),
            new SymfonyBundleAsseticBundleAsseticBundle(),
            new DoctrineBundleDoctrineBundleDoctrineBundle(),
            new SensioBundleFrameworkExtraBundleSensioFrameworkExtraBundle(),
            new JMSAopBundleJMSAopBundle(),
            new JMSDiExtraBundleJMSDiExtraBundle($this),
            new JMSSecurityExtraBundleJMSSecurityExtraBundle(),
            new myProjectMyBundlemyBundle(),
            new FOSUserBundleFOSUserBundle(),
            new myProjectMyBackendBundlemyBackendBundle(),
       );

        if (in_array($this->getEnvironment(), array('dev', 'test'))) {
            $bundles[] = new SymfonyBundleWebProfilerBundleWebProfilerBundle();
            $bundles[] = new SensioBundleDistributionBundleSensioDistributionBundle();
            $bundles[] = new SensioBundleGeneratorBundleSensioGeneratorBundle();
        }

        return $bundles;
    }

    public function registerContainerConfiguration(LoaderInterface $loader)
    {
        $loader->load(__DIR__.'/config/config_'.$this->getEnvironment().'.yml');
    }
}

Update III: .htaccess

DirectoryIndex app.php

<IfModule mod_rewrite.c>
    RewriteEngine On

    RewriteCond %{ENV:REDIRECT_STATUS} ^$
    RewriteRule ^app.php(/(.*)|$) %{CONTEXT_PREFIX}/$2 [R=301,L]

    RewriteCond %{REQUEST_FILENAME} -f
    RewriteRule .? - [L]

    RewriteCond %{REQUEST_URI}::$1 ^(/.+)(.+)::2$
    RewriteRule ^(.*) - [E=BASE:%1]
    RewriteRule .? %{ENV:BASE}app.php [L]
</IfModule>

<IfModule !mod_rewrite.c>
    <IfModule mod_alias.c>
        RedirectMatch 302 ^/$ /app.php/
    </IfModule>
</IfModule>

UPDATE: I have found the error, it was a wrong (old) render tag in a template. :(

Thanks for your support

I had this problem too, try to pay attention to your .htaccess and make it look like this:

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteCond %{REQUEST_URI}::$1 ^(/.+)/(.*)::2$
    RewriteRule ^(.*) - [E=BASE:%1]
    RewriteCond %{ENV:REDIRECT_STATUS} ^$
    RewriteRule ^app_dev.php(/(.*)|$) %{ENV:BASE}/$2 [R=301,L]    ##### this is the part that you should tweak, have the .htaccess point the request to app_dev.php, since the routing.yml is empty initially
    RewriteCond %{REQUEST_FILENAME} -f
    RewriteRule .? - [L]
    RewriteRule .? %{ENV:BASE}/app_dev.php [L]        ##### this is the part that you should tweak, have the .htaccess point the request to app_dev.php, since the routing.yml is empty initially
</IfModule>

<IfModule !mod_rewrite.c>
    <IfModule mod_alias.c>
        # When mod_rewrite is not available, we instruct a temporary redirect of
        # the startpage to the front controller explicitly so that the website
        # and the generated links can still be used.
        RedirectMatch 302 ^/$ /app.php/
        # RedirectTemp cannot be used instead
    </IfModule>
</IfModule>
