Hello,
Ok, you’re not receiving the emails because the reservation was not confirmed after the PayPal process. The status is pending. So the email notifications system is working. Emails in instant mode are sent after the confirmation.
The problem seems related to PayPal sandbox in your case.
I tried right now with a test installation and everything went fine. So there’s probably something wrong on your server or on your PayPal sandbox configuration.
First, in Hotelier > Logs check the PayPal log. Also, please note that PayPal works in this way:
1. You make a request to PayPal
2. After the payment, PayPal sends an IPN request to your server and that request is the one that confirms the reservation. In the log, you should find this entry” “Received valid response from PayPal”.
So your server must accept external requests and must be online of course. Check your firewall if any. If you can’t find that entry in the log, that’s the problem. PayPal is not able to contact your server and you need to debug it yourself.
