Latest version of J1.5, CB & CBsubs. Get "Return to Merchant" error using sandbox. Error also says, "The link you have used to enter the PayPal system is invalid. Please review the link and try again."
Noticed the button link has url different from my sandbox.
CBsubs button url:
www.sandbox.paypal.com/cgi-bin/webscr
My sandbox url:
www.sandbox.paypal.com/us/cgi-bin/webscr
Only difference is the "us" directory in the path.
Can I fix this? If so, where do I go to look for it?
I can browse php but do not know it.
Thank you,
Ray
