Redmine

Hi,

when I try to create a new issue for a project, I get an Internal Error :

WebPage :
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.

From the logs :
