Apptheme Vantage theme - stop new user moderation

Hi guys,

I'm looking for someone who knows the Vantage theme very well and who could disable/remove the moderation of the new user which is in place in Vantage. Because I have a membership plugin (RCP) which already manages the access.

Currently, in my setup, if I use the standard twentyone fifteen theme, my new users is directly registered after his payment and directly has access to the full website.
BUT When I activate Vantage, even If made it free of charge in the setup, it requests a approval of the admin to validate the new user registration. I don't want/need this.

Could someone help with this issue ?
(Pas de problème pour dialoguer en français, mais j'aimerais trouver qqun qui connaît déjà bien le thème)

Thanks in advance

Kind regards,

Antoine
