Disable new user registration mail only for user and not for admin

Luca,
I apologize for the delay. To disable just the user email, and not the admin email, you'd need to make a different modification in the same file.

Around line 495, you'll see:Comment out the 2nd line above, which is just for the user email. The rest of the code below that is for the administrator emails.

I hope that helps, but if you still have questions, just let me know.

Thanks,
Alex

Awesome! Glad to hear that got you going. Should you need anything else, just let us know.

Finally, if you haven't already, please consider leaving a rating and review for JFBConnect, or our support, on the Joomla Extension Directory. It certainly isn't required, but is very appreciated:

Thanks,
