Redmine

Hi,

I installed Redmine 3.3.2 on Debian 8, I'm able to login as admin, but when I try to create (Register) another user this Internal Error appear.

"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."

Here is the tail of the log:
