[sudo-sys] Re: sudoroom.org upgraded, help needed

So the old instance is still accessible at https://humans.sudoroom.org/ and I set up redirects, but logging in is now broken. Trying to log in returns "not a POST". I believe this is because some urls are hard-coded. Even with redirects, my guess is it's triggering some csrf protection somewhere. I could be wrong. Both sudoroom and CCL use this thing to make money. This is serious. Help would be very appreciated. Meanwhile, substack made a valiant effort to get sudo-humans working with node 17.x. We got partway, at least the front page displays now, but it still crashes when you try to do anything.
