Symfony 4 - 404 на страницах - стандартный htaccess файл

Стандартный htaccess файл для Symfony 4 чтобы убрать 404 ошибку на дополнительных страницах:
# Based on http://stackoverflow.com/questions/17313023/symfony-2-2-1-url-rewrite-issue
# Modified to use index.php as per symfony >= 4.0 installer

# Use the front controller as index file. It serves as 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
# startpage (path "/") because otherwise Apache will apply the rewritting rules
# to each configured DirectoryIndex file (e.g. index.php, index.html, index.pl).
DirectoryIndex index.php

<IfModule mod_rewrite.c>
    RewriteEngine On

    # Redirect to URI without front controller to prevent duplicate content
    # (with and without `/index.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 startpage 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} ^$
