[galaxy-dev] can not login to workflows after postgresql setup

Hi all, I have set up postgresql to work with galaxy because the standard mysqlite didn't work with my workflow. Now that postgresql seems to be working I can not login to galaxy. When I try to login it says that it can't find my username. And also when I click "forgot password" it says: "Mail is not configured for this Galaxy instance. Please contact an administrator." Any ideas? Kind Regards Jaap
