Hey. I got this message from PayPal regarding our integration with them. I have a Joomla site using DT Register and DT Donate and I am using the "Paypal Express" payment option. I am not sure what is throwing the error. Before I try and dig into this more, is there something inside these products that I should be aware of that I haven't configured? Or maybe it's a Joomla configuration issue? Or perhaps it is something I need to set up inside PayPal. Let me know if you have any insight.
Here is the message:
