wp-content/cache/ in URL when accessing HTTP

Hi, I’m trying to redirect HTTP to HTTPS with .htaccess, and now when I try to access the HTTP version of the website, I’m always taken to HTTPS and there is wp-content/cache/ in its URL. But this is not happening in every browser. For example, in Opera, I’m taken to the HTTP version.

In my .htaccess file, there is currently:

# BEGIN WpFastestCache
# Modified Time: 24-10-22 8:33:00
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
<strong>RewriteCond %{HTTPS} =on
RewriteCond %{HTTP_HOST} ^investmentalbania.com</strong>

…
…

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
RewriteEngine On
<strong># all redirection HTTP -> HTTPS
RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]</strong>
</IfModule>
# END WordPress

What should I do to make it work?
