My store loops at checkout

[jewels1]

hi

my store keeps sending people back to cart on checkout. Ive posted this in paypal area but all i got was a complaint that it wasnt a paypal issue so here i am on this site.There was nothing wrong for two years and i havent added anything new at all ....

 

here is the code for the checkout_shipping.php

*/

 

require('includes/application_top.php');

require('includes/classes/http_client.php');

 

// if the customer is not logged on, redirect them to the login page

if (!tep_session_is_registered('customer_id')) {

$navigation->set_snapshot;

tep_redirect(tep_href_link(FILENAME_LOGIN, '', 'SSL'));

}

 

// if there is nothing in the customers cart, redirect them to the shopping cart page

if ($cart->count_contents < 1) {

tep_redirect(tep_href_link(FILENAME_SHOPPING_CART));

I am wondering if the store thinks customers have nothing in their cart???? because it keeps sending customers back to shopping cart instead of directing them to payment

can anyone help?
