Why is Yii2 not following a link?

Question

Yii

Good day! Installed the basic Yii2 template (via Composer). Removed comments from urlManager and stopped following links. That is, any added character in the address bar gives a 404 error. What could be the problem? Thanks in advance.
PS I work in Linux

Answer 1

.htaccess in index.php folder

<IfModule mod_rewrite.c>
    Options +FollowSymlinks
    RewriteEngine On
</IfModule>

# Если это папка или файл, открываем его
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
# В противном случае перенаправляем на index.php
RewriteRule . index.php

URL manager:

'urlManager' => [
            'enablePrettyUrl' => true,
            'showScriptName' => false,
        ],

Answer 2

Good afternoon.
What symbol?
Have you written the rules for urlManager?
Let's get more information.
Well, what of that? What does linux have to do with it?
