Redmine

Hi,

I've installed Redmine 2.0.1 on Ubuntu 12.04 LTS.

I'm having the following problem. If a uses that's assigned to an issue updates it, if he adds a file to the update, then he has the following error:

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.

Can U help me please

Ciao

Francesco
