WHMCS stop send email after pay invoices

[Abdelkarim]

Hi.

WHMCS stopped sending emails when an invoice is paid.

1. Verified the connection of the account and the server. Also, it sends proformas and other emails.
2. Verified the Invoice Payment Consignaturetion template. It's active.
3. Configuration -> General settings -> Check to send PDF versions of invoices along with invoice emails is checked
4. Invoice checked to Send Email Check to Send Confirmation Email

But the system only sends the proforma invoices and does not send the paid ones.

I see the doc for debug problem but don't see anything.

 

I checked logs on my own mail server, and is simple.

 

WHMCS not try send email. Not error on communication. Onley stop action.

 

Best regards.
