Redmine

OOps, found the problem, apparently I was using the wrong settings.yml file. Took the original one from the .tar.gz, restarted everything and it's working. Sorry for the trouble.

Hi,

I already serched and found similar problems, but the solutions did not resolve my problem.
When I try to access the settings page from the administration menu, I get a page stating:
"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.

Back"

It doesn't matter what user try to access it. below some information about the system I'm running:

This all happened after an upgrading from ruby 1.8.7 and redmine 1.4, which was working fine.

I don't know if it is related to this problem, but when I try to access Gantt from projects, I get the same message, but with a different log error:
