I am trying to post a post to my MyBB server from a Python script, but try as I might, I can't get it to work. The request shows up in the forensic log and the headers are in the $_SERVER variable, but $_POST is always an empty array. The error log shows nothing, even at the debug level. I've already tried searching, but I haven't found anything that's helped. I already checked the post_max_size thing, which is 8M.

Another factor is that it's just my own requests which aren't going through. Browser generated requests seem to do just fine. I've looked and looked, but I can't find anything I'm doing differently that should matter.

Anyway, here is an example request.
