Helleo, I''m currently in trouble with acts_as_taggable, indeed, the system raises this kind of error in Rail 2.0.2. But this works with Rails 1.2.3. I do not know how to fix it. It seems that something is connected to the Rails version. have you hot any clues about what the problem could be? Thanks in advance.
