Comment 16 for bug 662204

You're facing this bug https://bugs.launchpad.net/authpuppy/+bug/711931 that should soon be corrected.

In the meantime, you should upload an empty installed.txt file in the web directory and manually put the databases.yml and authpuppy.yml

But wait a minute, is your web/ directory called html? and the apps/ config/ etc. directory are in html/..? If so, I'm afraid there is still a bug that should be corrected soon ;-)
