Please help, I dont understand the error and how to resolve this. I
upgraded my App from Rails 2.3.5 to 2.3.10

The simplest way to trigger this warning (it's not Rails-related BTW) is this:

$ irb

irb(main):001:0> class Foo

irb(main):002:1> end

=> nil

irb(main):003:0> Foo::Array.new

(irb):3: warning: toplevel constant Array referenced by Foo::Array

=> []

So it seems that in addition  to ActiveRecord::Base:Configuration there's another class called Configuration defined at the top level.

Did you define this class? If not, does any of your dependencies define this class?

Best regards

As I told before in Rails 2.3.5 it was working fine, even though was
showing this warning as well but even then I could change the theme, but
in 2.3.10 its not changing the theme.

That does not answer the question.

If you search your code for Configuration does it find anything?

In that case your simplest solution may be to change the name of the model.

If I change the model name, then I have to make a lot of changes in
many other Controllers and where its been called
and the migration too.
so I get a lot of error messages.

Can u get any idea from the below tree diagram that if there any change
possible can make it resolve the problem. I changed the configration
folded name in fedena_theme app views but didnt do anything


The Configration model's file tree is
App
|-Views
|_Configuration.rb

And this plugin fedena themes files tree is

App -Vendor - Plugins- fedena_theme
:
:_ views
:_Configuration
: _theme_select.html
:_themes

A few global search and replace changes should do it. You don't need
to change the controller or table name if you don't want to. I assume
you have the source under a source control system such as git, and
that you have good automated test coverage, which will make sure you
catch everything.
