Upgrade to Redmine the 1.0-stable completed successfully. Access to service has been fully restored.
Some problems were encountered in regard to gem compatibility with the i18n enabled templates. For future reference the error encountered when rendering i18n’ed templates was:
ActionView::TemplateError (missing interpolation argument in “%m/%{count}/%Y %I:%M %p”
Freezing rails 2.3.5 to vendor and editing vendor/rails/activesupport/lib/active_support/vendor.rb to depend on a version of the i18n gem lower that 4.0 fixed it. (i.e. gem 'i18n', '>= 0.1.3','<0.4.0') fixed it.
Also, issues with mod_passenger (404s on /login and sever other pages) when running in a subdirectory were fixed my renaming/deleting the .htaccess file in public/ — it was creating rewrite rules for fastcgi deployments, which clashed with URI routing.
Service is now fully functional and new Redmine features are available.
