Redmine

Hi all,

After some updates on my server, Redmine is working but I can't create new projects. When I add a new project, I get the message:

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.

Looking for the production.log, I found this:
