The Cart is Empty
The first time anyone tries to order something on my site they end up with a message telling them "The cart is empty".
The process is:
Add to Cart - Checkout
Paypal button selected
Paypal login and review
Once the Paypal site's continue button is pressed the customer is re-directed back to the Powerstore site and cart.php appears with the message "The cart is empty".
This only happens the first time someone tries to purchase something. The second time it works ok - they are redirected from Paypal to the pp_confirm.php where they can confirm the order and checkout.
I've tried inserting <?php if(!session_id()) session_start(); ?> at line 1 of the cart page.
I've tried adding session_commit(); after // WA eCart Redirect on the cart and pp_confirm pages.
Do you have any idea what else I can try to get this resolved?
