Alternatively, the best and most secure way to use simplitt is to compile and test it in your local machine.
You need to install a web server with php support: apache and php packages should be enough.
Upload just the content in
site/folder to your internet server and you will have a full static site in your internet server, dynamically generated in your localhost.
To compile in localhost is good because: you'll automatically get a local backup of your site; and you maximize the security of your server.
