Loggin in with Authlogic throws error I can't seem to debug. Any clues?

It is hard to answer this question from this log. It seems like you use a newer(?) version of Authlogic than needed. (There is a missing function call)

Do you have some more version information?

Rails / activerecord version is required

Authlogic 3.0.3 depends on activerecord >= 3.0.7

You can install an older fix version of Authlogic if you need an older like this :

gem install -v <version>

Then if you use rails, you can specify the correct version to use. ( in environment.rb in case of 2.X) If you use Authlogic 3.0.3 I suggest you use Rails 3.
