If you do not know what an IPN (Instant Payment Notification) is then you should check the following URL:

http://www.tipsandtricks-hq.com/ecommerce/wordpress-ecommerce-knowledgebase-523#paypal_ipn

WP eStore uses the IPN feature of PayPal to verify and deliver the digital product after a payment. If you receive an email similar to the following from PayPal then it could mean that your server is blocking the IPN notifications from PayPal:

-------------------------------------------------------------------------------------------
Please check your server that handles PayPal Instant Payment Notifications (IPN). IPNs sent to the following URL(s) are failing:

http://www.your-domain-name.com/wp-content/plugins/wp-cart-for-digital-products/paypal.php

If you do not recognize this URL, you may be using a service provider that is using IPN on your behalf. Please contact your service provider with the above information. If this problem continues, IPNs may be disabled for your account.
-------------------------------------------------------------------------------------------

You have three possible ways to fix this:

1) Contact your web hosting to find out why they are blocking PayPal IPN (maybe they have a firewall which is doing it). Maybe you are using a plugin that is blocking it (The bad behavior plugin is known to do this). Deactivate this plugin.

2) Turn off the IPN feature from WP eStores settings menu (This will mean that all the fancy "post payment" functionality will stop working).

3) Change your hosting provider and get a good one :) (there are plenty of good and cheap ones out there)

I prefer option 1 :)

PayPal is a well known payment gateway so I don't know why some servers or plugin block IPNs from PayPal.

Hello,

I contacted the Godaddy webshosting support and they told me that the problem was not from their side. Since I do not know much of programming, I have no clue as to what's going on. One quick question if I go to this URL http://rescuelightsmusic.com/wp-content/plugins/wp-cart-for-digital-products/paypal.php I get a blank page. What does that mean?

Thanks,
Mayu

I am not certain if the problem is with Godaddy or some other software that you are using on your server but from PayPal's point of view they are having issue reaching your server.

I tried to send a test IPN from PayPal sandbox to your server and it gave me the following error:

"IPN delivery failed. Unable to connect to the specified URL. Please verify the URL and try again."

The URL you mentioned is the URL where paypal sends the payment notification (The plugin then reads it and does it's post payment stuff)

Basically, something is blocking PayPal from reaching your server... if you happen to have another hosting from some other company you can quickly prove this theory by setting up the eStore on that server.

Hey Amin,

Thanks for the reply. I did some googling regarding godaddy not allowing IPN and went through a few URLS. Can you please have a look at these and let me know if I can add anything to the script? Here is the link http://forums.oscommerce.com/topic/233097-official-paypal-ipn-godaddy-issue-topic/. I am not sure of my client will want to change hosting companies. Is there any other solution that you can suggest?

Thanks,
Mayu

Just had a look at that URL. The workaround suggested in there doesn't apply to our scenario as the eStore doesn't use CURL for IPN validation.

Your client shouldn't need to change the hosting company... Godaddy should be able to investigate why PayPal is having issue contacting their server and address it. There must be thousands of Godaddy users who uses PayPal so I am sure they allow PayPal IPN... there must be some server configuration/setup issue on your clients account.

I googled 'IPN godaddy' and it seems like a lot of people are having trouble with IPN and goDaddy. Would this URL help me at all with getting back on track? http://pr0gr4mm3r.com/php/paypal-ipn-and-godaddy-hosting/

The example code in that URL is missing code after line 40. Not sure if it will help but if the example code was complete I could put together another IPN handling script for you to see if it makes a difference.

Hi Amin,

I played around a bit more with the plugin. I tried to do a transaction and it sent me (the buyer)a receipt of payment but I did not get an email that has an encrypted download link to the digital product that my client is selling. Would it help you if I gave you the account details so you could see if I have configured it properly? Until Feb 2, 2010 everything was working perfectly fine.

Thanks.

My problem of not getting an encrypted link in the email is still not solved. Nor does it go in spam folder. Could you please help me out with that?

Thanks.
