@bep Indeed. Did you see the image I attached? Until yesterday, it was writing “2016.” I wasn’t hoping for “0001.” Since I haven’t changed the templating language for this at all, I was wondering if I missed something.
For the site lastchange it takes the date or lastmod from the last Page (being the first page in the default sort) … it doesn’t check if that page actually have a date. What you see is probably a Zero date (i.e. date not set). Check the front matter of your latest addition.
That did it. I added an extra dummy page - contents/json/dummy.md to make a site-index.html that I write to site-index.json as part of a bash script and completely forgot to add a date in the yaml. Thanks much, @bep.
