For some reason, any new custom block I create on my Drupal 8 site won't display or render in the DOM after placing the custom block in the region that I want. I've tried clearing cache multiple times, but it's as if custom blocks stopped functioning.
I have a few custom blocks that are still working and displaying correctly (from before it stopped working), but I'm afraid if I change them, I won't be able to get them to display again.
Any ideas? Hope this makes sense.
