There was some update by paypal which required me to change a setting on my website. I had that done from a coder, but still 1 or 2 orders a day are not updated as paid on my website. I have attached the correspondence I had with the previous coder. His problem was that he never once looked at the actual orders that were not being updated and instead did everything from the paypal side.
My checkout is coded in ASP classic.
Here is the original message I received from Paypal to change my settings:
Please check your server that handles PayPal Instant Payment Notification (IPN) messages. Messages sent to the following URL(s) are not being received:

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.
Once you or your service provider fix this problem, you or your service provider can resend the failed messages from the IPN History page. If this problem continues, PayPal may disable the IPN feature for your account.
