I would like to ask because i could not find something around. Is there any possibility to disable the database upgrade from browser? Or maybe disable the button so users won’t be able to upgrade the database by their own until administrator will make the upgrade?
Either you do automatic update and the DB migration should be played automatically
Or you do manual update, then you know when the server should be “disconnected” (= be in maintenance mode) and also when the migration should be run. The message is there to tell everybody that Matomo is in instable mode (because code and DB are not synchronized). It cannot work at all.
