I read that tip here in other support tickets so yes, of course I tried it, it didn’t work.
The pages actually vanished from the list of pages (published, drafts or trash). I had opened tabs of them in my browser from like 10 min prior…
I manage a few wordpress sites since 2015 and I never would have thought that merely installing and activating a plugin could cause instant and irreversible loss of data.
Since then I was able to roll back to an earlier version using an incremental weekly backup, so “problem solved” I guess. An explanation would be welcome though.
