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
Cet e-mail est protégé contre les robots collecteurs de mails, votre navigateur doit accepter le Javascript pour le voir
and we will make sure it is working correctly.
Best regards,
Mark
