I have a Jekyll site, and comments have been working fine for years. GitHub dragged their feet on HTTPS support for vanity domains so I gave up waiting and flipped to Netlify and that migration was easy (as was the LetsEncrypt usage).
However, the Disqus comments have disappeared. I saw some advice on how to fix that in here but the admin interface for Disqus does not have the option that blog entry shows anymore :-(
Yes, I similarly registered the HTTP to HTTPS change in my Disqus settings.
How do I get comments back?
