Avoid resend
Warning message: To reopen this page Safari/Firefox must resend a form. This might result in duplicate purchases, comments, or other actions.
I am having this problem, leading to the fact that, if a user refresh their browser, the add to cart form is resending it leading to multiple element,
so if I say add to cart once, and then resfresh the browser without clicking on the add to cart button, I get the warning message above,
Any help please!
