Hi there, I am trying to figure out what went wrong. something very strange happened. When i click Add to Cart on the product page, the cart.php opens but it tells me that the Cart is Empty. If i hit F5 (refresh) it still tells me "Cart is empty". BUT when i click on the Cart Link on my menu, the page reloads and show me all my products in the cart. If i have 3 unique items in cart, when i try to delete only the first one, it tells me "Cart is empty" When i try to delete the 2nd or 3rd, it tells me "Cart is empty" AND i get this error message: Notice: Undefined index: cart_array in /home/_______/public_html/cart.php on line 76 And when i reload the page again, all the items are still in the cart. I am so confused. these is the code i have in cart.php : <?php session_start(); // Start session first thing in script include "storescripts/connect_to_mysql.php"; error_reporting(E_ALL); ini_set('display_errors', '1');
