Setting Up Symfony 2 - Cannot Load app.php Resource

Question

I'm having trouble with setting up my Symfony2 production environment. The dev environment through app_dev.php works fine, but production through app.php leades to a 500 Internal Server Error, and this message in the Symfony error log:

[2011-08-28 10:09:11] request.CRITICAL: Symfony\Component\Config\Exception\FileLoaderLoadException: Cannot load resource ".". (uncaught exception) at /var/www/Symfony/vendor/symfony/src/Symfony/Component/Config/Loader/Loader.php line 75 [] []

Don't know how to solve this, or even stack trace it...

Answer 1

Happened to me when I updated the Liip/ImagineBundle.

In older versions of this bundle it required this in your routing:

_imagine:
    resource: .
    type:     imagine

In the new versions this is to be replaced by:

_liip_imagine:
    resource: "@LiipImagineBundle/Resources/config/routing.yaml"

So in my case the problem was I updated the bundle via composer, but did not update the routing.yml.

I had the same problem. Try to add:

assetic: use_controller: true

in /app/config/config_prod.yml and clean cache after that (rm -fr /app/cache/*)

Answer 3

if you have these problems in production environment and you use assetic, then check if you don't have this:

_assetic:
    resource: .
    type:     assetic

in your config file (normally this is in config_dev.yml only, not in production)... in other case try to check other routes with resource: .

I had faced a similar issue while hosting symfony2 project to a godaddy windows shared hosting with php5.3 support and fixed it by providing write permission to the symfony2 directories and creating an iis virtual directory for the symfony project directory.
