**Your software** My Mautic version is: 5.0.3 My PHP version is: 8.0.28 My Database type and version is: MySQL 8.0.35 **Your problem** My problem is: Seems like when using PHP8.0-FPM on my NGINX, MAUTIC 5.0.3 works OK. ✅ But… when I switch the MAUTIC site over to PHP8.1-FPM, I get the red offline message (see screenshot). ❌ What am I missing? Could anybody please direct me on how to move MAUTIC to PHP 8.1? ![mautic_screenshot](https://us1.discourse-cdn.com/flex020/uploads/mautic/original/2X/a/a0b97757addd2cc57865d557df8e10a2ab14c83d.png) These errors are showing in the log: Steps I have tried to fix the problem: ---

Please provide logs from `/var/logs `. My guess some PHP extensions are not installed. Also I would try to install composer packages. ---

I’ve installed every imaginable PHP8.1 extension and when I switch over from PHP8.0-FPM to PHP8.1-FPM on NGINX, I still get that red error message so I have to switch it back to 8.0 for it to work again. Are you sure MAUTIC 5.0.3 supports PHP 8.1? ---

Well… For some reason, 5.0.3 runs on 8.0 but not on 8.1. What’s missing? ---

Did you install all the necessary php extensions and reinstall php dependencies using php 8.1? What is the error that you are getting ? Best, M.
