Redmine

Hi to all,

I'm new to redmine. I've migrated the redmine from old server to new server and everything is seems to be good. But when I click an existing issues its showing error like 'Internal error'. My production log shows below error.

ActionView::Template::Error (undefined method `send_to_owner' for #<Journal:0x00000005f60040>):
16: <%= render_notes(issue, journal, :reply_links => reply_links) unless journal.notes.blank? >
17: </div>
18: </div>
19: <= call_hook(:view_issues_history_journal_bottom, { :journal => journal }) >
20: < end >
21:

Also I've done below steps after importing the database.

rake db:migrate RAILS_ENV=production
rake db:migrate_plugins RAILS_ENV=production

But still I'm getting same error.

And I've ran the query too: "update issues set parent_id = NULL, root_id = id, lft = 1, rgt = 2;"
