When I activate Appointments+, the copy from most of my web pages disappear and only the title is left. Deactivate Appointments+ and it's fine. I've been running this plugin for 2+ years with this same theme and they were always fine. I have not added any other plugins besides WPMUDEV plugs in (wp-smush, smartcrawl, hummingbird). I'm not sure when it stopped working, I wasn't informed until today.
