Hi,

I just upgrade from 2.2.2 to 2.3.2 and the following error when trying  
to start the server

=\> Booting Mongrel  
=\> Rails 2.3.2 application starting on [http://0.0.0.0:3000](http://0.0.0.0:3000)

I figured out that by commenting out the validators.rb (http://  
[pastie.org/457289](http://pastie.org/457289)) that I used so far it’ll start up fine.

Apparently the issue lies with valid? but I can’t figure out how to  
fix it.

Does anyone know how to go about this?

Cheers,

JM
