After Upgrade to Rails 3.0, all translation missing: en

HI All,

I’ve just succeeded to upgrade my rails to 3.0.

However, all my translation are missing no matter what locale I set.

I can run ‘rake makemo’

and I tried to add and remove the following I18n.backend in my
application.rb

I18n::Backend::Simple.send(:include, I18n::Backend::Fallbacks)
I18n::Backend::Simple.send :include, I18n::Backend::Gettext
I18n::Backend::Simple.send :include,
I18n::Backend::InterpolationCompiler

My Gemfile:
gem ‘gettext’
gem ‘i18n’

Please help! I am frustrated…

Arthur
