About HTTP to HTTPS Redirect

[ImagjneAlex]

The website's .htaccess file is as attached. The site has SSL installed, but it can be accessed via both http and https. I want to redirect http to https. I've tried a few methods, but even when it redirects to https, it displays the site's FTP files and the script doesn't work. RewriteEngine On RewriteCond %{REQUEST_URI} !^/public/ RewriteRule ^(.*)$ /public/$1 [L,QSA]
