perhaps you can close all old thread.
since there is some bug/error that we found at old version but not exist at 2.1.1 but it comming back at 2.1.2
it’s must be different error with same title (make confusing)
Any example of such threads?
some of new reply/post are replying from old thread/inactive thread … like post from 2020 and middle of 2021
i dont know is this cms have ability setting to “auto close” in active post with x month
