I'm currently having issues with a site that's running WP Emember. The script is unmodified.
According to Paypal's IPN history it is sending details to the IPN script successfully but when buying the user doesn't get their username or email sent to them and no account is created. When the subscription is cancelled through Paypal written to the debug file is
[01/31/2012 5:28 PM] - SUCCESS :Retrieving member account from the database...
[01/31/2012 5:28 PM] - FAILURE :No member found for the given subscriber ID:
So it is definitely connecting with the script but when the user subscribes nothing is written to the debug file and their account is not created.
I cannot tell what's going wrong so was hoping that some one may have had experience with a similar issue.
