Ok, I deleted everything and started from scratch thinking that maybe I missed something along the way. Nope. And I find zero documentation on using Paypal sandbox in terms of eCart. What am I missing here?
Ok, so how do I test an existing eCart 5 site using PayPal Standard in the sandbox?
And then when I am done testing, how to I flip it over to PayPal live?
If it's in server behaviors can you point me to specific ones? What pages?
Again, this is PayPal Standard. Thank you!
