Callback to online store is failed
I received this message on 11/10/2013 -
"Callback to online store is failed. This notification has been sent by X-Payments installation at 'www.mysite.com'"
Now all credit card transactions are failing and the credit card fields for secure checkout on my website are missing.
I've had X-Payments installed and working since June 2012. I use PayPal Payments Pro as my payment gateway. I'm wondering why all of a sudden I'm having this issue and what I need to do to correct it.
I am using X-Payments version 1.0.4.
Thank you.
