Email on FB registration not sent

The email is sent by Joomla itself. Are you receiving other emails sent by Joomla, like the New User admin notification? Even then, that may be going through while the other isn't if it's to a different mail address.

With different configurations of SPF keys, domain keys and other spam prevention, some mail is deleted before it even makes it into your spam box.

I'd recommend:
* Trying to register from a different email domain
* Changing the "Mailer" in Joomla from SMTP to PHP (or vice versa), to see if the mailer subsystem helps the issue

Keep me posted if you can't get things going. We'll gladly test on your site, but every case of an email not being sent in the past has been due to server configurations (either not actually sending or not being configured as a valid sender).

Thanks,

We think we just found the issue here. If you have the "Send New User Emails" setting disabled in JFBConnect, that was preventing *all* new user emails from being set. The next release will properly send the new user activation email in the case that a) you have activation enabled, b) don't have JFBConnect skipping activation, and c) regardless of the "Send New User Email" setting.

Let me know if that seems like the likely cause for you. That setting should basically just be 'on' for now if you require activation to make sure it's properly sent.

Thanks,

If you upgraded to Joomla 3.2.0, you may be affected by a bug in Joomla itself. You can read more about it in this Joomla forum thread . The simple solution is to go into the Global Configuration area of Joomla and simply apply settings (if that doesn't work, try to change the mailer setting to something else, save, and revert it back again).

Let me know if that helps. We're not aware of any other email issues, but will gladly help to keep investigating if necessary.

Thanks,

Once activated, the user can login with their social network credentials regardless of their username.

As for the activation email, the username and password for the account will be included if you have the "Generate Random Password" setting "enabled". Without that, the user won't have a password for their account.

If you want, you can edit the strings that are used for the email in our /language/en_GB/en_GB.com_jfbconnect.ini language file. The main strings to look at are:
COM_JFBCONNECT_EMAIL_REGISTERED_WITH_ACTIVATION_BODY_NOPASSWORD (if no password is generated)
COM_JFBCONNECT_EMAIL_REGISTERED_WITH_ACTIVATION_BODY (if password is generated)

I hope that helps,
Alex
