I've been working on a C# app to post to the Atom API. It was working for a while, but then when I did a post, I got an HTTP 409 (conflict) response. Now every post I send fails. If I post to a different blog using the same account, the content goes through successfully.

When I look at my blog, I see that my posts sort-of went through... They're listed as drafts. I didn't use the draft flag in my query, however.

I'm doing a POST to https://blogger.com/atom/29947750

<?xml version="1.0" encoding="UTF-8" standalone="yes"?><entry xmlns="http://purl.org/atom/ns#"><title mode="escaped" type="text/plain">testing title</title><issued>2006-06-24T01:24:44.624Z</issued><generator url="http://www.sean-smith.com">Sean</generator><content type="application/xhtml+xml"><div xmlns="http://www.w3.org/1999/xhtml">Testing content</div></content></entry>

The exact same post to https://blogger.com/atom/30167409 works fine.

Any idea what's causing the conflict? Each attempt is a new post. I'm not ever trying to edit posts.
