Redmine

I am currently running a production Redmine server with 2.3.3 and wish to test 2.4.0-1. I do not have any plugins loaded.
However when I backup the SQL database and import it on the 2.4.0-1 install, I am prompted with the Redmine login screen to which I enter my username and password then am prompted with the following.

*Internal error

An error occurred on the page you were trying to access.
If you continue to experience problems please contact your Redmine administrator for assistance.

If you are the Redmine administrator, check your log files for details about the error.*

I am doing the backup as per the instructions [ mysqldump -u root -p bitnami_redmine > redmine251113.sql
Import to 2.4.0-1 [ mysql -u root -p bitnami_redmine < redmine251113.sql

If I check the log file for red mine I see the following.
