[FIXED] Symfony 3.4 Website returns 404 on js and css resources

Issue

I have no experience with Symfony and my PHP is very rusty (last time I worked with it was at version 4).

I would like to host a copy of this website: https://thronesdb.com/
It has a public git repository located here: https://github.com/ThronesDB/thronesdb/

After following the instructions of README.md and making some minor adjustments to the location of the web folder I got it to kinda work: https://ccgdb.uber.space/

Not sure if relevant:
Due to limitations imposed by my hosting provider I was not able to use Options +FollowSymLinks in .htaccess but instead resorted to Options +SymlinksIfOwnerMatch.
Additionally, since Apache seems to be configured to not allow access in any folder except /var/www/virtual/ccgdb/html (which is my document root), I moved the whole folder I got when checking out above mentioned repository in /var/www/virtual/ccgdb/html/ccgdb and copied all files from /var/www/virtual/ccgdb/html/ccgdb/web to /var/www/virtual/ccgdb/html.

The website itself loads and functions perfectly fine. But most of the resources (.css and .js files) return 404s. I have no idea where to look next.

Any hints or ideas how to resolve those 404s?

Content of .htaccess:

# Use the front controller as index file. It serves as a fallback solution when
# every other rewrite/redirect fails (e.g. in an aliased environment without
# mod_rewrite). Additionally, this reduces the matching process for the
# start page (path "/") because otherwise Apache will apply the rewriting rules
# to each configured DirectoryIndex file (e.g. index.php, index.html, index.pl).
DirectoryIndex app.php

# By default, Apache does not evaluate symbolic links if you did not enable this
# feature in your server configuration. Uncomment the following line if you
# install assets as symlinks or if you experience problems related to symlinks
# when compiling LESS/Sass/CoffeScript assets.
Options +SymlinksIfOwnerMatch
#Options +FollowSymLinks

# Disabling MultiViews prevents unwanted negotiation, e.g. "/app" should not resolve
# to the front controller "/app.php" but be rewritten to "/app.php/app".
<IfModule mod_negotiation.c>
    Options -MultiViews
</IfModule>

<IfModule mod_rewrite.c>
    RewriteEngine On

    # Determine the RewriteBase automatically and set it as environment variable.
    # If you are using Apache aliases to do mass virtual hosting or installed the
    # project in a subdirectory, the base path will be prepended to allow proper
    # resolution of the app.php file and to redirect to the correct URI. It will
    # work in environments without path prefix as well, providing a safe, one-size
    # fits all solution. But as you do not need it in this case, you can comment
    # the following 2 lines to eliminate the overhead.
    RewriteCond %{REQUEST_URI}::$1 ^(/.+)/(.*)::\2$
    RewriteRule ^(.*) - [E=BASE:%1]

    # Sets the HTTP_AUTHORIZATION header removed by Apache
    RewriteCond %{HTTP:Authorization} .
    RewriteRule ^ - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]

    # Redirect to URI without front controller to prevent duplicate content
    # (with and without `/app.php`). Only do this redirect on the initial
    # rewrite by Apache and not on subsequent cycles. Otherwise we would get an
    # endless redirect loop (request -> rewrite to front controller ->
    # redirect -> request -> ...).
    # So in case you get a "too many redirects" error or you always get redirected
    # to the start page because your Apache does not expose the REDIRECT_STATUS
    # environment variable, you have 2 choices:
    # - disable this feature by commenting the following 2 lines or
    # - use Apache >= 2.3.9 and replace all L flags by END flags and remove the
    #   following RewriteCond (best solution)
    RewriteCond %{ENV:REDIRECT_STATUS} ^$
    RewriteRule ^app\.php(?:/(.*)|$) %{ENV:BASE}/$1 [R=301,L]

    # If the requested filename exists, simply serve it.
    # We only want to let Apache serve files and not directories.
    RewriteCond %{REQUEST_FILENAME} -f
    RewriteRule ^ - [L]

    # Rewrite all other queries to the front controller.
    RewriteRule ^ %{ENV:BASE}/app.php [L]
</IfModule>

<IfModule !mod_rewrite.c>
    <IfModule mod_alias.c>
        # When mod_rewrite is not available, we instruct a temporary redirect of
        # the start page 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>

Solution

Since I changed the original web-root from web to html I followed these instructions: https://symfony.com/doc/3.4/configuration/override_dir_structure.html#override-the-web-directory

Except I didn't follow the last step regarding the AsseticBundle. After doing that as well, everything is working now.

Note to self: RTFM
