Redmine

Hi,

I have redmine setup and have some project in it. Every project is having its git repository. Whenever I commit and push in git, the redmine projects didn't fetch that commit automatically.
I have gone through with http://www.redmine.org/projects/redmine/wiki/HowTo_setup_automatic_refresh_of_repositories_in_Redmine_on_commit
but this didn't worked.
Then I checked the logs and here's the output of that

App 7563 stderr: Processing by SysController#fetch_changesets as HTML
App 7563 stderr: Parameters: {"id"=>"balvinder", "key"=>"XXXXXXXXXXXXXXXXXXX"}
App 7563 stderr: Rendered text template (0.0ms)
App 7563 stderr: Completed 404 Not Found in 3ms (Views: 1.0ms | ActiveRecord: 0.2ms)

Is there's any solution for this.?
