I'm using git but none of the changes I made had anything to do with auth. I
ended up pushing the app (identical code) to another fluxflex project
(http://ianwscott.fluxflex.com/Paideia) and the login works fine. So it
looks like the issue wasn't with my code update but with something on the
server. I also re-initialized the faulty project with a new web2py
installation on a cleaned directory, but had the same problem. So somehow
there seems to be a server-level issue with that project. Unfortunately
servers are largely a mystery to me, so I'm not sure how to go about fixing
it. Thanks, though.
