When a user wants to create an account on the website, i got an error : "Error sending email: An email must have a "To", "Cc", or "Bcc" header.".
Others emails as test email, contact email, runs perfectly.
User is registered, but no confirmation email is sent.
Before, it was ok for that and i do not change anything.
The user account activation policy contain just body and subject.
Thanks for help.
