PayPal Order Missing

I was able to get my PayPal standard module working so that it automatically sends the customer back to my website to the checkout success page but there is still no order number on the page. It says "your order number is" but gives no number. There is no order in the Admin and no email is sent to the customer with the order details. The payment receipt is sent from Paypal just fine.

What am I missing?

For Website Payments Standard to complete, PayPal needs to be able to talk to your server behind the scenes. There are many factors that can come into play to interrupt that. See this article for troubleshooting steps: http://www.zen-cart.com/wiki/index.php/PayPal

Keep in mind that it's always a good idea to include your Zen Cart version and a list of any installed addons when you post a request for help ;)

I have two issues when connecting to paypal standard.

1. When the customer gets transferred from my store to paypal's website to make payment; only the billing address get transferred to paypal. In case the customer has a different shipping address; the payment page - 2 on Paypal shows the billing address in place of the shipping address.

2. Say the customer enters paypal's website for final payment and for some reason he/she returns back to my store->changes the billing and/or shipping address -> returns back to paypal's site for payment again. The old original billing info is being displayed in place of the new changed addresses.

Will you be able to shed some light into this issue?? Greatly appreciated..
Thnx much
Iam using zencart 1.3.8
Also tried changing to 'no_shipping'==2, in paypal.php but it didnt help.
