community builder email validation administrator does not work

Hello, I installed the latest version of CB 2.5.0
I have asked to receive an email to the administrator to validate when a new user registers. But I never receive this email.
The user does receive the email to validate his email, but the administrator should then receive one to validate this registration. But I never receive it.
This is the same problem as here www.joomlapolis.com/forum/145-community-builder/230874-solved-cb-2-0-10-validation-email-not-send but the solutions do not not work.
Thanks for your feedback

User approval is done after confirmation. So you will not receive an email to approve the user until they've confirmed their email address.

Thank you but I validated on the link I received and I have this message displayed.

Thank you for confirming your email address. Your account must be accepted by a moderator. You will receive an email with the result of the validation process.

But I still don't have an email for the administrator

I recommend downloading and read the CB Primer Book found below.

www.joomlapolis.com/downloads/documents

Page 106 covers configuring moderator emails. Be sure CB can even email you first though by using the Mass Mailer button in CB > User Management after selecting your user.
