Symfony3 – Assets not working properly in Production

My SF3 application is working just fine in dev built-in PHP server. However some assets give me an error when getting to a production Apache server : the images are showing a 404 error, and a Bundle triggers a 505 code. Here’s 2 screens of the Chrome console where you can see the errors :

Dev:
Prod:

I’ve been trying many things (checking the Apache conf files, emptying the cache, the install:assets command even thoug I’m just using the classic Twig syntax and no Assetic, etc) and browsed tons of topics over the internet in vain.

Here’s my config.yml file just in case :

imports:
    - { resource: parameters.yml }
    - { resource: security.yml }
    - { resource: services.yml }
    - { resource: "@ABundle/Resources/config/services.yml" }
    - { resource: "@AnotherBundle/Resources/config/services.yml" }

        #   1. add the path in parameters.yml
        #     e.g. database_path: "%kernel.root_dir%/../var/data/data.sqlite"
        #   2. Uncomment database_path in parameters.yml.dist
        #   3. Uncomment next line:

I’m really stuck on this one, so thank you in advance guys.

Answer

have you tried: php bin/console assetic:dump --env=prod --no-debug ?

also, your assets should be in src/YourBundle/Resources/public directory. Then when you install them with php bin/console assets:install --symlink they should be copied or symlinked to web/bundles/your directory
