I have a donation page where I'm using gravity forms with the authorize.net addon.
See here:
https://www.thehumanesociety.org/wp/donate/
When I use the "force ssl" checkbox in the credit card field my donation page starts looping, and just keeps refreshing the page over and over.
I installed the WordPress HTTPS plugin the forced that my donation page to be secure. The looping stopped but the "This page is unsecured" message in the credit card field still shows.
I called my host and had them scan the page and they confirmed the the page was secure with an SSL certificate.
Any ideas on how to fix this?
