There is no 404 .htaccess redirect when using CNC. Why?

Question

PHP

Good day! When writing the site, there was a need to redirect to the 404 page, but the script written in .htaccess does not work. Routing on the site occurs according to the scheme: mysite.com/controller/action/id.
How to fix?
The content of the .htaccess file

Options +FollowSymLinks
<IfModule mod_rewrite.c>
    SetEnv HTTP_MOD_REWRITE On
    RewriteEngine on
    ErrorDocument 404 /error404.php
    RewriteBase /
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)$ index.php?_route=$1?%{QUERY_STRING} 
</IfModule>

Answer 1

You need to remove RewriteBase /
You are redirecting to the main page, so that you do not enter, if there is no such page, it will go to the main one. By default index.php
But this can be fixed))
