Live Activity suddenly stopped working. I posted a query here and got no reply. Uninstalled Wordfence and dropped its database tables and things are faster.
Perhaps the devs mean well, and when it worked it was interesting to see where people were visiting from, but when that feature stopped working it brought up the possibility of other features, like those related to site security and not as easily verified, also not working.
Let's just leave this at promising right now. But not production-level.
