Wow, we've been working on a bug that we recently discovered that causes entries to not post. The server would respond as though a page didn't exist or something similarly as bad. It turns out that there is a security rule on the server that has been blocking things if it is at all suspicious. This could definitely apply to comments and other things too.
This bug has probably existed for many years. It saddens me that I never noticed it. Kudos to Mark and Beth for being in tune with what is going on. Hopefully this leads to a better user experience.
I really feel like we've made significant progress on the site in the past week. It's looking and feeling much more like what Bloop used to look and feel like. I love seeing entries actually get posted.
It's good to be back!
