I've added a lot of users and groups today, but now I suddenly run into problems. I tried adding an e-mail address to a user, but when I hit the save button, I get the message: "The user information could not be saved". I tried making changes to other users, all give the same error.
Some more tests I've done:
I can add new users. When I add an e-mail address to this new user and hit save, I get the same error. When I then go to another user, hit No (don't save changes, because that gives an error), and then go back to the user I just created, the e-mail address I added but couldn't save, is still listed. So it saves the changes, but still complains.
I can't delete any user anymore.
Adding/modifying/deleting groups still works fine.
I've rebooted the entire server to make sure everything is started up correctly, but still the same error.
I've also noticed, that my administrator-user (login name administrator), does not have a first name (anymore?). Can't remember if he ever had a first name, but I think so.. because for all users I added, first- and lastname was needed. Also, at the e-mail adresses part it says "Scalix Administrator" <sxadmin@mydomain.com>. Lastname of the admin-users is Administrator, so my guess is that his first name once was Scalix

I don't know how/where it did go wrong, and don't know how to resolve this problem.. please help
