The good news is I installed Beta 2 on a fresh Debian 10 setup. I followed the Perfect Server tutorial and it all went spiffingly well apart from when it failied to get a Letsencrypt certificate for the server/control panel. It defaulted to a self-signed. The Letsencrypt log pointed to the failure to set up an account due to an invalid email address [[email protected]$hostname]. I'm pretty sure I inputted a valid address& FQDN whenever prompted elsewhere but can't exclude finger trouble. I then did the usual 3.1 trick of setting up a site and sharing its certificate. That worked so certbot appears to be working OK. Any ideas on where the missing address/hostname is? NB hostname -f displays expected FQDN. PS I discovered you have moved the favicon into the theme. Fixed that but its worth a note on the changelog unless I missed it.
