Order Paid For, But No Receipt or Order in Admin

[tagdealz]

Hello...

I have a new problem that popped up. From Day 1 - about 3 months ago, I set up Zen Cart and Used the Paypal IPN Setup. My only payment method.

40+ Orders have been placed and no issues.

All the sudden the past 9 orders have had the following problems..

Customer Places Order and Pays Via Paypal.
- In paypal, i see the following showing that it is comming from the site

Item Title:
Website Purchase
Item Number:
Store Receipt
Custom:
zenid=4i56fp3n4nnjplmu6h7uqdq5p2

Almost all my items have attributes that allow for the customer to download the product after payment. Now I never get a Order Receipt, the Order does not show up in the ZenCart Admin (although the customer account does) and the customer never gets the product to download so I have had to email the product to them manually.

Sorry if this has been answered somewhere before, But I could not find any help regarding this issue.

Thank You...
