I'm experiencing a really weird issue. When I fork the active_admin gem and use the forked, unchanged version it gives me the following error:
Sprockets::CircularDependencyError in Active_admin/devise/sessions#new
/Users/Victor/.rvm/gems/ruby-1.9.2-p180/bundler/gems/active_admin-916ecdd04e3c/app/assets/javascripts/active_admin/base.js has already been required

12: <%= javascript_include_tag path %>
13: <% end %>
14:
15: <%= csrf_meta_tag %>
When I use the original version there are no errors. How is this possible if the two versions are identical?
Yes.you can remove the line
//= require_directory ./
in
/.rvm/gems/ruby-1.9.2-p180/bundler/gems/active_admin-916ecdd04e3c/app/assets/javascripts/active_admin/application.js
Remove active_admin.js from your app/assets/javascripts folder - it looks like it is no longer needed.
I am running a pretty straight forward Rails 3.2 app on Dreamhost (I know its lame).
The error is:
NoMethodError in Products#edit
Showing /home/emeraldcityguitars/emeraldcityguitars.com/releases/20120318040051/app/views/products/edit.html.erb where line #47 raised:

It sounds like #product is returning nil, but if you look at line 44, it didn't error when requesting #product in that case?
any ideas?
EDIT

I had the same problem and I made two changes, unfortunately not separately, and one or both solved the problem.
First, in your controller do you build a photo in your edit method?
#product.photos.build if #product.photos.empty?
I found that in the comments on this blog post.
Second, I added a symbol for the nested class to the 'link_to_add' line, which you already have.
I was switching from a has_many to has_one and was getting this same error. Azolo's response fixed my issue.
Removed the <%= f.link_to_add......%> tag and all is working nicely!

I found this question : Rails heroku help kaminari view error. So i'd delete (and backup if necessary) your current views and regenerate them again

I have tried altering the the quotes and brckets and different errors are listed but the problem doesn't go away.
Any help would be great thanks.
You need commas between the arguments in the image_tag method:
<%= image_tag('logo.png', :alt =>'Sample App', :class =>"round" ) %>
