Redmine

I see. I use redmine 0.9.4 with Rails 2.3.8 and though it's supported fine because it has 2.3.5 for 0.9.x and 1.x versions

redmine SVN Updated to revision 4050. (RAILS_ENV=production rake db:migrate has been executed already)
ruby 1.8.7 (2010-08-16 patchlevel 302) [x86_64-linux]

Debian, Ruby1.8, Rails 2.3.5

It's driving me quite mad.

something strange there. I couldn't try a new version of redmine, still use 0.9.4 :(

Look at my entry. I had the same problem and could solve it by running a simple sql.

Hope this helps,

Thanks, that UPDATE did it.
