There are errors (" Could not insert new word matches") and new posts do not seem to be displaying. PMs do not appear to be notifying people (I sent a PM to two people, one a MOD, and neither has checked their PMs yet, I believe they are unaware of having received any).
I have seen 3 total posts in SE++ in the last ~20 minutes. I have posted several posts in one thread that I cannot see from the main SE window, but if I go into that thread and hit the reply button I can then see my posts in the "topic review" area and only there.
I hope someone sees this and can fix the issue.
