Thank you for the forgot password, much appreciated.
As for the cart, when the user is logged in, then https://ifrm.org/ifrm/convention-new.php click on the add to cart button, it does not go to the cart (../cart/cart_pp.php), it goes to itself and is a blank page (same address). I had to replace it with convention.php to go directly to PayPal so it works until I can figure out the convention-new page to our own cart. I did the same thing with membership page, Try membership-new.
