If I want to demonstrate to a potential customer SERP features such as postcode lookup or webshop card payments, how do I enable a demo system so I can do that?
This is not the issue of upgrade SERP. But serverip.dat in this case contains the value: 192.168.88.12:1301, so this is local IP of the server with SERP.
Anyway I don't understand what do you me...
