Ok, now is working.
The first time, I used only the email in presentation in edit plan.
The email on expiration was only sent if the user was connected to the site.
I installed the plugin cbsubs email, and now the email on expiration is sent when I visit cbsubs in backend. Even if I use 5mn in regular validity duration.
I have 2 others questions:
1- The email on expiration is sent at the end of the grace period. Why?
It would be sent at the date of expiration. Like this, the user would be able to reactivate the plan during the grace period.
2- If the user choose the recurring payment with paypal.
And if his credit card is expired for the second payment or after, paypal doesn't send the payment.
So what's happen in this case?
The plan is expired or unsuscribe
Thank you
