1.7.2 - Sending to multiple email addresses not working

Hi. on 1.7.2 sending to multiple email addresses does not work. Trying to save the client information already returns an error - “The Email Address field must contain a valid email address.” Addresses are comma separated as per the previous version. Where do I look?

application/modules/mailer/views/invoice.php
application/modules/mailer/views/quote.php

The field to_email contains “multiple” and that is wrong.
I’ll try to resolve it in the develop branch for you so that it will be in version 1.7.3

I was checking my records and this issue was actually around when I upgraded to 1.6.3. in August 2025. At that time the bug was resolved, but I cannot locate the fix. I am hoping it might be similar.

I just think the issue resurfaced when dealing with several vulnerabilities.
It means it was gone and it came back and that … is regression (it’s one of the worst kinds of bugs)

As long as you make that tiny change you’ll be fine until version 1.7.3 gets released
