There are no relevant errors in the web server log or php log files.

Site health check shows no relevant issues: https://i.imgur.com/4USskOH.png

I have redownloaded and installed the WP core files. No change in problem behavior.

I have disabled all noncritical plugins. No change in problem behavior.

Have also rebooted the host just to make sure this isn’t some weird transient issue, and the problem behavior persists.

As noted at the top, I have reinstalled the classic editor plugin so that my users can create posts while I troubleshoot, so I’m not down, but any advice or assistance on what to troubleshoot next would be appreciated. Thank you 🙂

(Adding the two image links has gotten this post marked as spam. Sorry. Not sure how else to share the relevant info.)

I seem to have fixed the issue!

Cloudflare was for some reason serving out outdated js files. I dumped my Cloudflare cache and things started working again.

Let this be a lesson: it’s always either caching or DNS. One of those things is probably the problem, always.
