I am trying to use PayPal Developer Sandbox Testing. I understand how it works, I tested my cart a month ago and it worked fine. At that time in my Payment Gateway settings for PayPal I had the Secure URL to your Gateway's server set as https://www.sandbox.paypal.com/xclick/business
Now this does not work, instead of taking me to the payment page where I select PayPal or Credit Card etc. it keeps telling me I need to log in to my sandbox which I already am. Has the address changed to the sandbox or what is the problem? Any help would be appreciated.
I am using AgoraCart Store Manager ver 5.0.001
