I went into my behaviors on my detail page, changed the button add to cart to:
I have the site in test under karenshotz.com/test/ filename
After I changed the redirect for the button, I saved the file then I went back in to the button behavior and it had not changed...it was still cart.php
Also, is there any code that I need to add to the pages indicating the https? How does the button know the page is https?
