Opened an account with pagekite, and installed it after. I noticed that the old name in configuration remains. Do I have to change the FB hostname and Domain name in Configuration after that to reflect pagekite’s kite name? Anything else must be done to use other apps?
FreedomBox will handle the domain in ‘Configuration -> Domainname’ (hostname has little relevance) very similar to domain configured in Pagekite. For many apps, you will be able to use them on both domains (if they work) or select one of the two domains. There are rare exception for apps like matrixsynapse that once configured with a domain can’t be modified later.
Feel free to change domainname in configuration to Pagekite domain name if the old one does not work.
