What is paypal ipn contribution and where do you install it or copy the code for it to work?

 

Thank you

Hello

 

The paypal IPN is used to show what products where ordered at your shop in the paypal site, because without this if someone pays by paypal and does not hit the continue button on the checkout page, you will get the money, but you will have no idea what they ordered. ( its basicly not to make you look stupid)

 

Change your entire paypal.php page to this,

located in \catalog\includes\modules\payment
