Ok I'm sorry. Cpanel really shouldn't let you upgrade gems to incompatible versions .
Anyways, I've downgraded all of my gems and have replaced the require rails/all with what it does ie:
require "rails"
%w(
active_record
action_controller
action_mailer
active_resource
rails/test_unit
).each do |framework|
begin
require "#{framework}"
rescue LoadError
end
end
However, it can't seem to find "rails" and mongrel gives this error:
/home/tashman/rails_apps/BattleShipApp/config/application.rb:4:in `require': no such file to load -- rails (LoadError)
from /home/tashman/rails_apps/BattleShipApp/config/application.rb:4
Is rails also part of Rails 3?/Is there any equivalent for rails 2?
I might have to try setting up a local environment in rails 2 to see how apps start. Been using Rails 3 prerelease so I have no experience with the previous versions.
Thank you for your help Geoff.
