After installing brand new 4.4.1 instance with MYSQLI adapter the system check widget complains about lack of UTF8mb4 support. There is no such warning when PDO adapter is used.

Expected Behavior

No warnings. Presumably MYSQLI is equally supported.

Current Behavior


Possible Solution

Steps to Reproduce (for Bugs)

  1. Perform a fresh new install of 4.4.
  2. select MYSQL adapter
  3. continue through interactive setup
  4. Observe the following warning


Your Environment

Using official docker approach:

  • Matomo version: 4.4.1
  • MySQL version: 10.6.4-MariaDB-1:10.6.4+maria~focal
  • PHP version: 7.4.23

I also repeated the same clean install with RDS Aurora (mysql 5.7 compatibility), and observed the same problem.

@dominikborkowski Did you maybe have a look at the full system check and not only the widget. The widget tooltips might sometimes be misleading - see https://github.com/matomo-org/matomo/issues/18006

You're right, the tooltip is misleading, the full system check indicates the same exact problem as seen in the issue you linked:


Can we merge this issue with the one you linked? EDIT: On a second thought, I think there is an important distinction. The problem I describe here manifests itself right away after a simple install, not by changing an existing database afterwards.

@dominikborkowski I will close this one as duplicate of #18006. It doesn't make a difference if it's a fresh setup or changed database settings.
