We created a form to allow users to pay a monthly bill with the authorize.net addon but it is displaying an error message on the credit card field. We have an SSL certificate but the credit card field comes with a red banner saying "This page is unsecured. Do not enter a real credit card number. Use this field only for testing purposes." I have looked around the forum and googled any solutions but haven't found anything that could solve the problem, any help is appreciated, thanks.
