@davidlemaitre I just checked the plugins and they should be definitely compatible. By any chance are you still seeing this message and can you post a screenshot of what you see or maybe you took a screenshot when it happened?

I'm still seeing this message from administration area :

Note : I'm using the official 3.14-apache version of Matomo Docker image, I pulled the new image to get the 3.14 version instead of automatic update.

Thanks @davidlemaitre

Can you check if the files $matomoDir/plugins/LogViewer/plugin.json and $matomoDir/plugins/TasksTimetable/plugin.json exist and paste the content of these files here maybe?

The LogViewer and TasksTimetable directories are missing. I reinstalled them, the warning message has been disappeared, all is fine.

I think I have to put the plugins directory or the whole Matomo in a Docker volume. Currently, only the config directory is persisted in a volume.

Thanks for letting us know and glad it works now 👍
