Hello-
I recently reached out to the Authorize.net help desk and they sent me here. Below is what they told me:
[So we recently started having issues with the simple check out where that error you are receiving would come up. Our engineers have discovered the issue and here is the fix that they prescribe: "After a recent release (CHG1155405) we no longer allow merchants to use the Simple Checkout form in an iFrame due to security concerns. Any merchant doing this will see the error above:" "Simplecheckout.authorize.net refused to connect" "If a merchant is using the simple checkout in an iframe they will need to update their site. " From this response they are saying, that you will need to reach out to your web developer to update the website accordingly. If you do not have a developer or need to help update the page or remove the Iframe. I would suggest making a post to the Developer Forum.]
We would like some guidance on what we need to do to fix this error. Thank you!
