Since around 23:00 CET Sunday, e-conomic has not been available. We are working hard to solve the issue. Sorry for the trouble, more info to come.
Update 00:50 CET Monday: Issue found, e-conomic is up and running again.
Error was a due an overfilled transaction log and the notification system for this situation failed, unfortunatly. We are taking steps to make sure this will not happen again.
Sorry for the trouble.
