Some time ago (trying to fix something else) I switched my web host to run PHP version 7.2, and didn’t notice that doing so had broken the glue code that made my Clarion Journal entries work.
When I did notice that it was broken I didn’t fix it right away. Partially that was because I had been meaning for some time to import all those journal entries into the WordPress blog. (Among other things, that would mean all those entries would be properly included in my site map.) More to the point, it was because fixing it would require debugging and coding PHP, something I hadn’t done in more than 10 years.
Today, though, I got email from a guy who had tried to read my journal and had found it missing, and that turned out to be the kick I needed to go in and fix the PHP code. (The fix turned out to be utterly trivial.)
