portofacil Okay. Thanks. I'd already manually updated the alternatives to version 8.0. I've since added a couple of WordPress sites, and it seemed to work fine (I'm giving it more time before fully switching to 8.1).
A couple of other things I've done is update opgui.php manually (it now supports PHP 8 and JIT stats) and eXtplorer (updated to address security issues and support PHP 8). To use the updated version of opgui.php, upstream.conf also needs to be updated:
# Multi PHP upstream for WordOps backend
upstream multiphp {
server unix:/var/run/php/php81-fpm.sock;
server unix:/var/run/php/php80-fpm.sock;
server unix:/var/run/php/php74-fpm.sock;
}
It's all become a bit "hacky" but at least it saves me from switching to an alternative in the short-term.
