Form not Secure
My homestead site on sitebuilder plus is secure (https://). I created a new page with a form that when submitted takes the user to a secure payment page. However, when they hit submit using an IOS device, it says "This form is not secure, Are you sure you want to submit it?" If you choose yes, it just locks up. It submits fine on my HP laptop. Can anyone explain how to correct this issue. Page in reference is https://coatesvilleindiana.org/warda.html which takes them to warda-payment.html when submitted. Please advise thank you.
