Redmine

*Hello all,

I hoping that somebody will be able to help me get my instance of redmine up and running.
I've installed the latest packaged release, and it is reachable on the intended subdomain. The problem is that I can't login using the admin:admin default credentials.

I am redirected to a '500 internal error'

The production.log file contains:*
