plugin breaks issues view

[camous]

Hi there,

I've tried to install the plugin onto this environment

    Environment:
      Redmine version                2.4.2.stable
      Ruby version                   1.9.3-p484 (2013-11-22) [x86_64-linux]
      Rails version                  3.2.16
      Environment                    production
      Database adapter               MySQL
    SCM:
      Subversion                     1.8.8
      Filesystem                     
    Redmine plugins:
      redmine_cors                   0.0.1

I've installed the plugin in my redmine plugin folder (where all other plugins)
/usr/share/redmine/lib/plugins

ran the rake command

    /usr/share/redmine# rake db:migrate_plugins RAILS_ENV=production
    Migrating redmine_cors (Redmine CORS)...
    Migrating redmine_image_clipboard_paste (Image Clipboard Paste)...
    Note: The rake task db:migrate_plugins has been deprecated, please use the replacement version redmine:plugins:migrate

but unfortunately, after apache2 restart, I'm getting the following error on rendering (the plugin information showup correctly on admin page)

Processing by IssuesController#new as HTML
  Parameters: {"project_id"=>"ez-billing"}

I'm not really used to ruby/redmine plugin mecanism (more a sharepoint admin ...) so I'm a little bit lost on the rootcause. Any help, advice would be great. (I have full hand on the system).

many thanks ! hope I will be able to maek it work in order to push more my co-worker using it :)

I believe that this issue belongs to redmine 2.4.2, because it knock out the issue view on the same redmine release on Ubuntu 14.04 server too.
The issue links shows correctly in project listing but when user click on the link system throws a 404 error: => “404 The page you were trying to access doesn't exist or has been removed.”
