Codeigniter 4 Multisite

I have installed Codeigniter 4 on Raspbian and everything seems to be working fine. My web directory is /var/www/html Inside there are two folders containing two different Codeigniter-4 apps that I would like to invoke with:

blue.ddns.net -> /var/www/html/blue/public/index.php
black.ddns.net -> /var/www/html/black/public/index.php
So I'm creating a .htaccess file to put in the folder /var/www/html/ to handle the two requests

Well, I'm still at step 0 because omegle shagle voojio I can't get the .htaccess file to work properly.

Below I attach a copy of the file:

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /var/www/html
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)$ blue/public/index.php?/$1 [L]
</IfModule>

<IfModule !mod_rewrite.c>
    ErrorDocument 404 /index.php
</IfModule>
The Rewrite module is activated the error that appears in /var/log/apache2/error.log is:

/var/www/html/.htaccess: Expected </IfModule> before end of configuration, referer: https://blue.ddns.net/
