Community Auth: Can't login

Again, I cannot respond to you via PM, because you have not enabled PMs.

You're problems point to something outside of Community Auth, and without having physical access to your server there's nothing I can do or suggest. Since I, using your code and database, was able to make it work, you'll need to either provide physical access to your server, or debug on your own.
