A lot of warning messages of deprecated

Hi guys, I installed Matomo recently in a PHP 8.1 shared server by DreamHost and I got a lof ot warnings about deprecation.

Which version of Matomo do you currently run?
Are you sure the PHP version is not 8.2?

Yeah @heurteph-ei, you’re right, I defined PHP 8.1, but hosting updated to 8.2 without my consent.

I returned to 8.1 and works fine, thanks.
