Thank you. Now I see.

The issue is not anyhow connected with PayPal. In fact, it doesn't even have anything to do with Ecwid. The reason why such links return 'Page not found' error is the custom code you use on your site. In the source of your store page, I found this code:

  if (window.location.hash.indexOf('#!/') == 0) {
        window.location.replace(window.location.hash.substr(2));
    }

That code changes page URL when the address contains hash part - it simply removes that part and redirects customer to a non-existant page, which results in the error you saw.

In order to fix the issue, you will need to remove that code.

Is there any way to determine which sales come from which site?

Yes, please refer to this article:
