Undefined array key “address” in /includes/class-settings.php on line 474

Thrice on every WP Admin page load, the following error appears in my error log:

[25-Oct-2025 03:17:52 UTC] PHP Warning: Undefined array key "address" in /public_html/wp-content/plugins/constant-contact-forms/includes/class-settings.php on line 474

Here’s the problem in bold:

line 473: $business_name = $disclosure_info['name'] ?: $business_name;
line 474: $business_addr = $disclosure_info['address'] ?: '';

Both of these lines directly access array keys without checking if they exist first. If the key is missing, PHP 8 will throw an “Undefined array key” warning.

The fix is to replace those Elvis operators with null coalescing operators, like so:

$business_name = $disclosure_info['name'] ?? $business_name;
$business_addr = $disclosure_info['address'] ?? '';

Would you be willing to fix this bug in your next plugin update?

Thanks!
