Security Warning after customer processes CC using Authorize.net

I have searched threads for this issue, however have not seen this addressed. If there is a thread, can someone post the link?

After the customer fills out the CC processing form via Authorize.net and submits, they get the attached warning page. However, the process authorizes no matter if the customer agrees or disagrees. I sent a help email to the developer side of Authorize.net and received a reply to contact ZC.

Under the module settings in ZC, the suggestion of leaving these fields blank are my current settings from within Authorize.net:

Your "response" and "receipt" URL settings in your Authorize.net Merchant Profile can be left BLANK, or can be set to point to http://your_domain.com/foldername/index.php?main_page=checkout_payment

I suspect that your pages are partially encrypted

A link to your site will take the guessing out of the mix

OK, I have to ask the obvious question, which did you opt for? leaving it blank, or pointing to the URL?

I'll wager that you set it to point to the URL, which WILL produce the error message that you are receiving (at least on some browsers).

You have two options:

1. Leave the URL setting blank
2. Change the URL to use https://Your_domain.com/foldername/index.php?main_page=checkout_payment.
   Note: Your store must be SSL enabled for this to work. Else it'll produce an even more serious security warning.

IMPORTANT: I've never used Authorize.net. I've never read or seen any suggestions regarding any of these settings. My response is based soley on the screenshot and information that you have supplied. I could be WAAAAYYYYY off track.

pss: Make sure any/all URL's TO Authorize.net are SSL encrytped. (You don't need an SSL enabled store for this one).
