Not sure if this is a bug or a server configuration problem. After switching from PHP 8.0 to 8.1 on my hosting server I now get the following error email every hour when the archiving cron job runs.

Go back to php8.0 there is 0 need to have the newest PHP. Most security issues have other causes than the php version.

Its a hosting provider issue. Look for a professional set up or go VPS.
