It’s amazing what you can fix by looking at a problem again after leaving it alone. After the server change, OS upgrade, new install, etc., one would think that everything would be simple. Well, it actually is. One of those odd little things that you need to do if you are using “pretty permalinks” is to fix the default apache configuration to allow overrides on file info. That was the whole issue. It made sense later when I remembered I had been running the old webserver and configuration for better than 10 years (with lots of changes).

Like I said. Amazing!
