On a new installation of ClassicPress 2.7.2, there don’t seem to be any feeds. https://example.com/feed/ and Example Domain both give 404. I must be missing something basic?
The support bot altered my input. Where it reads “Example Domain” in the OP, what I typed was https:// example .com / ?feed=rss2/ ( without the spaces). In other words, adding /feed/ or /?feed=rss2/ to the site’s URL gives 404.
This was a fresh install, and unless it had me update as part of that and Im not remembering, I don’t think updates are involved.
