I am working on my client's website https://gerrykeane.ie/ and when I add a product to the cart I get promoted a warning message that the form page is not secure. I have updated the security certificates to my domains , but that page that is throwing error is https://gerrykeane.ie/checkout/cart/. There is a link being used in the form redirection that is not secured as I am trying to find a way to edit that to https (http://gerrykeane.ie/checkout/cart/updatePost/)

Any help will be welcome.

Thanks Nipun
