CSS and JS files aren't load by the twig templates

[ALECSQY]

Hello,

I'm new with this bundle, it's the first time I use it. Iupload and install it in my project -Symfony 3.2- and after installing the config.yml, l lost the link with my assets(CSS, JS, IMG...).

What happened ? Here my config:

`nelmio_security:
# signs/verifies all cookies
signed_cookie:
names: ['']
# prevents framing of the entire site
clickjacking:
paths:
'^/.': DENY
# prevents redirections outside the website's domain
external_redirects:
abort: true
log: true

# prevents inline scripts, unsafe eval, external scripts/images/styles/frames, etc
csp:
    hosts: []
    content_types: []
    enforce:
        level1_fallback: false
        browser_adaptive:
            enabled: false
        report-uri: %router.request_context.base_url%/nelmio/csp/report
        default-src:
            - 'none'
        script-src:
            - 'self'
        block-all-mixed-content: true # defaults to false, blocks HTTP content over HTTPS transport
        # upgrade-insecure-requests: true # defaults to false, upgrades HTTP requests to HTTPS transport

# disables content type sniffing for script resources
content_type:
    nosniff: false

    mode_block: true

# Send a full URL in the `Referer` header when performing a same-origin request,
# only send the origin of the document to secure destination (HTTPS->HTTPS),
# and send no header to a less secure destination (HTTPS->HTTP).
# If `strict-origin-when-cross-origin` is not supported, use `no-referrer` policy,
# no referrer information is sent along with requests.
referrer_policy:
    enabled: true
    policies:
        - 'no-referrer'
        - 'strict-origin-when-cross-origin'

Resolved,

I'd chosen the maximum security level, whik transform your website in Fort Knox. Adding directives with the URL and 'unsafe-inline', all is good now.
