I'm getting the following error.
Warning, the Safe path is empty, for safety reasons it is very important to create a folder in a path not accessible by an URL, create also a folder invoices in it to store your sensible data secure. Our suggested path is for your system /home/xxxxx/public_html/vmfiles
I created the path in my system, but it still shows up.
