The only things I can think of are that maybe the rest of your templates aren't readable to the web server, or you're using the "unfixed" version. I'll look for your e-mail so I can see it in action.
As for upload/debug not working (login required), the URL that's part of album.tml won't work because it just has a hard coded "function=upload" in it. (It also won't work if you change your upload code...)
Of course, if you're using cookies, that shouldn't be a problem, but that doesn't cover all cases.
