Still not working but an interesting thing happened, between yesterday and today. Yesterday the text “[toc]” showed up in my public post. Today, it does not. So today, it recognizes it as a code but does the wrong thing with it.
I went ahead and submitted a question. I’m going to go ahead and publish that post. It only has two headings anyway. If my article, two articles ago, didn’t have a table of contents, that would not have been good.
Question: should I try uninstalling the plug-in and re-installing it? Would that put my existing posts at risk? The tables of contents are working in existing posts. It’s just new ones that are having the problem.
