Both those files are there, but __init__.py is empty. I did a fresh quickstart, and the file is empty in that too, so I don't think anything is especially wrong there.
Thanks for thinking on it. In the meantime, I found a workaround. It seems to be something about code_dir not working - if I move my project dir into the webfolder, and change any PROJECTNAME.xxx references to PROJECTNAME.PROJECTNAME.xxx references, it works. I'll see if I can find the glitch later.
