I did go to settings > permalinks, set to post name, save changes. post is published and set to public. also updated theme, core, plugins. Then I went through and deactivated unused plugins one by one. Eureka! I think it was a Redirect plug in causing problems. looks like someone installed it years ago, but it wasn’t actively collecting information. It’s now deactivated. Should I delete it all together?
Right now I’m trying to finish links in this newly created page.
When I’m finished with all the updates I want to make, I’ll revisit plugins and delete items I find not in use.
Thanks, Felipe!
