I was trying to use some IndieWeb plugins (Post Kinds in particular), but had not updated my site in a while (I think I was at 4.7.13). I took a look at Chris Aldrich’s site and saw that he was using WP version 5.3.2, so I decided to make the jump. Overall, the upgrade went smoothly. I downloaded the Classic Editor plugin so that the Post Kinds plugin would work. I was also prompted to update all of my existing IndieWeb plugins. After all of that, I still had some problems with the Post Kinds plugin for the Read post kind (I was not seeing the Post Properties window within the Admin interface. I started to write a Github issue, but then went back to a Chris Aldrich post on the Post Kinds plugin, and saw that I wrote a comment on that post about this problem. Chris replied with a suggestion to  click on the Screen Options tab in the top right hand corner of the admin UI and then check the Response Properties box. That worked!

So far, so good….
