I've made some changes to be able to get things working - mostly - on PHP8.2. The latest issue is the version of HTMLPurifier. There is a version that is PHP8 compliant and I've begun testing with that. There are some changes to how things get loaded that are different, so it will take a bit of effort. If you disable HTMLPurifier (not recommended if users are allowed to post), the core appears fully functional on PHP 8.2.
