UsersOnline Module Not Populating/Working in DNN

I have recently setup an DotNetNuke 4 based CMS at http://www.biharmirror.com/
The UsersOnline module was not showing any users/members online. I have done following to get it working:
1. Gone to Host Settings/Advanced Settings/Other Settings. Unchecked Disable Users Online?
2. Gone to Host/Schedule. Edited the Schedule PurgeUsersOnline like this:



After waiting for some time (about 1 minute) it started working automatically. As you can check at http://www.biharmirror.com/
