ProudToBeFout you need to identify which version of PHP you have on your server.
Then you likely want the "Zip" format with "Public path: No". If you are running PHP 8.3, that's the very first file at the top of the list.
The installation then works like WordPress. You open the website in your browser, and that's where you enter the MySQL credentials. Flarum will then create the database and config file.
