EE 6.1.6 / PHP 8.1.1 on Apache 2.4.51: issues because in PHP 8.1 the Serializable interface is deprecated
News and General
I just installed EE 6.1.6 on my development PC which is running PHP 8.1.1 on Apache 2.4.51 (and mySQL 8.0.27).
After logging into the CP there are 10 “Deprecated” messages displayed above the dashboard (which shows further deprecation messages). I’ve copied the messages below for reference.
Through a quick search I found the following information on php.watch: PHP 8.1: Serializable interface deprecated
This looks like a bug to me, but maybe I’m missing something? Does somebody know more about this issue (which prevents me from using EE at this point).

I don’t think EE is fully compatible with PHP8 just yet so things like this I’d suggest logging as a bug at https://github.com/ExpressionEngine/ExpressionEngine/issues
@Rob is correct. EE is not fully compatible with PHP 8.1. If you want to check this out and see if addresses everything you’re seeing, here’s the PR for 8.1 support in EE 6.2 https://github.com/ExpressionEngine/ExpressionEngine/compare/feature/6.x/php-8.1-compat.
What is the latest version of php that is fully compatible with EE? Or do you have an estimate on the release of EE 6.2?
EE 6 is compatible with 7.4.
Version 6.2 is planned to be released tomorrow (Jan, 12). Watch the blog, Twitter, and Slack for more information.
