Redmine

Before we investigate, can you give us the output of a ruby script/about ? Did you run the migrations correctly before it occurred ?

I ran the migration.

I don't think it's a database migration issue. I'm pretty sure that the app was not properly restarted.

JPL - my sequence was:

1. Deploy new code.
2. Run migration
3. Restart unicorn and Apache.
4. Unable to create user.

Then:

1. Restart unicorn and Apache.
2. Problem still exists

Then:

1. Re-run migration.
2. Restart app.

Finally I ran the migration a third-time and it made the required changes and I restarted and it worked. The first two times it seemed like it didn't pick up the migrations?
