At some point during my recent WordPress > Hugo migration, a lot of cruft was introduced into both my front matter and the body of my posts. This caused my posts to stop showing up in my Micro.blog account, due to feed errors. I did not catch this for awhile since I don’t post that often. The feed was, in fact, invalid. During the early stages of troubleshooting, I removed the RSS output from home, and – of course – forgot about it.
Thank you for catching this - no telling how many hours of frustration you may have saved me!
