UPDATE: I just tried this with using PayPal as the payment processor. The “ipn_handle_debug.log” processed everything fine (the payment went through, I received the product email, etc.). When it kicked over to the “subscription_handle_debug.log”, the same error was posted:
FAILURE :Member signup email sending failed
Is there something I’m missing? The integration with WishList is fine, since the temp registrations are being created correctly. But I’m wondering if I have a piece somewhere that’s not quite right. It’s not the WordPress email system, since the product emails are being sent without a hitch. And it’s not a bug in eStore itself since I just used this same build for a different client (I’ve been recommending the software to everyone I can!) and her’s is working just fine. Puzzling!
