By default, the script will work without secure connection (https), except Facebook/Twitter login features. Yet it's highly recommended to turn on redirection (http to https).
.htaccess

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . index.php
</IfModule>
<FilesMatch "\.(gitignore|htaccess|env|env-example)$">
