[chef] cannot access chef-server-webui and display "ActionView::Template::Error" in chef-server-webui log

[idzzy < >]

Hello,

When I access to chef-server webui, it’s displayed "We're sorry, but something went wrong”.

And output following log in /var/log/chef-server/chef-server-webui/current

---------------------------------------------------------------------

2014-08-06_06:08:10.53840 ActionView::Template::Error (undefined method `each' for nil:NilClass):

2014-08-06_06:08:10.53840     15:           %select{:name => 'environment-select', : 'jump(this)', :size => 1, :class => 'title-select'}

2014-08-06_06:08:10.53840     16:             - current_env = session[:environment]

2014-08-06_06:08:10.53841     17:             %option{:value => environment_select_url('_none'), :selected => current_env == nil} None

---------------------------------------------------------------------

This phenomenon seems to be similar these cases.

https://tickets.opscode.com/browse/CHEF-5301

https://tickets.opscode.com/browse/CHEF-5307

Base on above cases I have already tried to modify like this 3 patterns and did "chef-server reconfigure".

/etc/chef-server/chef-server.rb

    chef_server_webui['cookie_domain'] = ‘'

    chef_server_webui['cookie_domain'] = ‘.mydoman'

    chef_server_webui['cookie_domain'] = ‘mydomain’

But still displaying same error message and cannot access chef-server webui.

How can I fix this issue?

Thank you.
