Zen Cart 1.5.0, as part of PCI Compliance, emails the shopowner every time something changes in the admin. While this is a good safety feature, it’s not desirable on test carts. Here’s how to turn it off:
Edit the file includes/functions/functions_email.php
At the start of the function zen_mail() add the line
if ($module == ‘admin_settings_changed’) return;
This will bypass the sending of notifications on admin changes.
