I have a site I maintain, mostly from a design standpoint. I know some PHP, enough to make some changes but am having an issue that I cannot figure out and hoping someone here can help me.
From what I know, this seems to be happening only in Firefox.
They add an item(s) to the cart > click Proceed to Checkout > it says "You have no items in your cart."
Thank you for any assistance or guidance you can give me to resolve this.
