After PayPal checkout, emails are received with the registration link missing and "error" reported.
Using the payment method inside Wishlist Memger everything is added and mailed OK.
The IPN log is blank.
In the setup instructions you say "add POST URL" to the ipn handler file from the Integration page. There isn't a URL with that label, but I assume that this URL is the URL with the return to the registration page. I also can't find the "Secret Word", but assume its the key from Paypal.
If these assumptions are not correct, that may be my problem.
Thanks
Don
