I am having this same issue, but on a dedicated server.

I had the same problem yesterday after my docker containers had been updated. The error message hints about a compatibility issue with the latest MariaDB image and Wallabag concerning the database charset. I changed "image: mariadb" to "image: mariadb:lts" in my docker compose file and it solved the problem.

What do i do on the standalone server side? (Debian 12)

For my part, I didn't go that far. I rolled from "iimage: mariadb:latest" to "image: mariadb:11.3" ... waiting for Wallabag to evolve.

When not running on docker, I still encounter this error. What should I do?
