Redmine

this is the Redmine and plugin I used for the last year without a flaw on some one elses server.....dont know what server.

Redmine version                2.4.3.stable
  Ruby version                   1.9.3-p484 (2013-11-22) [x86_64-linux]
  Rails version                  3.2.17
  Environment                    production
  Database adapter               Mysql2
 redmine_backlogs               v1.0.6

This is the Redmine we just installed on ubuntu 14.04

Environment:
Redmine version 2.4.3.stable
Ruby version 1.9.3-p484 (2013-11-22) [x86_64-linux]
Rails version 3.2.16
Environment production
Database adapter Mysql2
Redmine plugins:
no plugin installed

But can't get the same plugin installed.

Does anybody have a fix for this......I don't care what version Redmine is but I need that redmine_backlogs V1.0.6 plugin
