Hi there,
have just updated my PayPal app to the latest. All went well and live it all works no problem retrieves balance etc.
I use PayPal Standard and Bootstrap
My site uses SSL sitewide and is compatible with all PayPals new requirements. server TLS 1.2 etc. I have even run PayPals tests for the new requirements and passed them all.
However when I use the Sandbox I get a blank page. Maybe I am using the sandbox incorrectly?
Anyone have any ideas?
