Hello!
I'm Anna, Ecwid team, thank you for the message!
From what I can see, right now the URL PayPal sends the instant payment notifications (IPN) to is not valid and returns 404 error.
I checked your Ecwid account and I can see that you use PayPal Standard payment option. In order for this payment method to work properly in your store, the IPN should be set up correctly.
Thus, please, follow the steps below to check the settings of your PayPal account:
1) log in to your PayPal account and open Profile > Profile and Settings > My Selling tools page
2) find "Instant Payment Notifications" line and click "Update" > "Choose IPN Settings" button and select Receive IPN messages (Enabled) option.
3) paste the following URL to the "Notification URL" field:
http://app.ecwid.com/paypalstandard/STOREID, where STOREID is your Ecwid account ID (
how to find it).
4) save the changes.
As you do this, the IPNs should be delivered fine to Ecwid.
More details on how to setup PayPal Standard payment method in your store are provided in this article:
