I installed OpenProject 3.0 but i can’t publish news.

The internal error is:

“An error occurred on the page you were trying to access.
If you continue to experience problems please contact your OpenProject administrator for assistance.
If you are the OpenProject administrator, check your log files for details about the error.”

I’m administrator, i’ve installed on Ubuntu 12.04, the OpenProject version is 3.0.

Cheers.

Did you set up everything correctly as the manual advises? What’s the error message that you get in your command line when running the server from the commandline? Maybe your mail smtp connection is wrong.
