trouble booting Webrick after unpgrading Rails

I recently upgrade from Rails 2.1.0 to 2.3.2 and now get this message when I try the app and start Webrick:

=> Booting WEBrick

Has anyone seen this problem or understand what’s happening here?
I’m using Netbeans 2.7 beta

thanks for help

Seems like you should upgrade active_scaffold as well.

Geoff,

This is the core mailing list for discussions of rails core, such as tickets or feature requests. For help, please ask this on the rubyonrails-talk mailing list.

It looks from the stack trace like ActiveScaffold is trying to alias_method_chain a method that no longer exists, you are probably using an old version of ActiveScaffold, try upgrading.

P.S.: The Ruby on Rails Talk list at http://groups.google.com/group/rubyonrails-talk is the more appropriate forum for this.
