Redmine

I have spent the past few days trying to upgrade Redmine from version 2.2.3 to version 2.3 without success.

First, my environment info:

Debian Squeeze
Phusion Passenger 4.0.10
Ruby 2.0.0-p247 (installed using RVM)
MySQL 5.1.66

$ RAILS_ENV=production script/about
/home/redmine/redmine/redmine-2.3/lib/SVG/Graph/Graph.rb:3: warning: class variable access from toplevel

Environment:
  Redmine version                2.3.2.stable.12039
  Ruby version                   2.0.0-p247 (2013-06-27) [x86_64-linux]
  Rails version                  3.2.13
  Environment                    production
  Database adapter               MySQL
Redmine plugins:
  no plugin installed

I tried following various different tutorials but keep hitting problems with the db:migrate script. Recently though, I managed to get most things working again by creating a blank database, running db:migrate on that and then finally applying a database backup on top of it.

I can view tickets, modify them, etc. However, going to the Settings page for a project gives a 500 with the error log:

Completed 500 Internal Server Error in 13ms

This ticket: http://www.redmine.org/issues/13757 recommends doing a db migrate in order to fix this. However, doing so gives me the same error I have been wrestling with for a while now:

==  AddTrackersFieldsBits: migrating ==========================================
-- add_column(:trackers, :fields_bits, :integer, {:default=>0})
rake aborted!
An error has occurred, all later migrations canceled:

Tasks: TOP => db:migrate

I started trying to modify the database migrate scripts so that they only add new table columns if they do not already exist. I gave up on this after realising how big a job this is. Surely I'm on completely the wrong tracks. Please help.

Thank you.
