Have you tried switching to a different theme? It’s possible it’s a similar issue as we were having with bbPress. WordPress should be pretty malleable. May be handy to keep a copy of the base theme without changes just for testing purposes.
Speaking of which, we lost the link we used to fix bbPress when Teams was flushed to the mutant alligators. Are you able to dig it back up? I’m thinking it may be helpful to make notes of our changes 🙂
On an encouraging note, some of the Teams data at least is still there. I had turned off the tablet before I went out of town and before your last post. I turned it back on after we got locked out and received a notification on the tablet with your last post. Couldn’t access it, of course, but it was there. Hopefully that means we’ll be able to access it again in the future
