You get this message when Omeka can’t send the activation email for a user.

I believe you may have had to redo your server recently, so you might not have installed or set up the software needed for sending mail, something like Postfix for example. Omeka just relies on the server’s setup for mail and doesn’t really handle it itself.

Even with the mail not working you can manually set passwords for users after creating them and manually mark them as active, though.

Perfect.
I install postifix and now is ok.
thanks very much for your help
