Hi phonroth701 -
Tableboss uses the underlying Joomla! mail function. Can you try to create a new user with an email address you can check and see if an email gets sent there.
If the email is sent to the new user, but the confirmation email is still not sending, we can take a look for you. Please add a super administrator account for
Diese E-Mail Adresse ist gegen Spam Bots geschützt, Sie müssen Javascript aktivieren, damit Sie es sehen können
and we will make sure it is working correctly.
Best regards,
Mark
