[UNCONFIRMED] Bug in steps when handling invoices, can corrupt proper invoices track

[Clueless Script Breaker]

Hello,

 

WHMCS 5.1.3

Steps:

1. Have GD extension for PHP disabled

2. Mass pay invoices or order a new product

 

People mass pay their invoices. The merged invoice is marked as paid, but the individual ones remain unpaid.

 

New customer's order get an invoice on their order, but the invoice is not linked to their order. Once paid, the order due date remain in the past although all invoices are paid. The order shows "No Invoice Due" although there was an invoice generated.

 

It seems WHMCS creates the invoice, fails at generating the invoice for sending by email and stops there midprocess, leaving broken invoices. I'm not sure how to link the invoices to the orders now. It seems the invoice generation should be moved after the WHMCS process for adding the invoice and linking it correctly with orders/merged invoices is completed. Otherwise if WHMCS chokes on creating the invoice to send, the process gets half-done. This way if there's issues with sending the invoices, they can simply be re-emailed.

 

This is just a guess on the issue that occured but that seems to be what happened.

 

Regards.
