Symfony3 - Assets not working properly in Production - php

Question

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" }
# Put parameters here that don't need to change on each machine where the app is deployed

# if using pdo_sqlite as your database driver:

# 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 1

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

Answer 2

So the problem was that my assets were in the web folder instead of the Resources. Then the assetic:dump command worked perfectly.
Thanks a lot
