I see that Contact reCAPTCHA is shown as compatible with Zen Cart 1.3.8.

I have it working with 1.3.9d but I note that includes\modules\pages\contact_us\header_php.php is one of the files replaced in the latest upgrade.

Are there any implications to using the older version in the Contact reCAPTCHA archive?

Is there a need for a new version of Contact reCAPTCHA?

Regards

Nick
