i have been trying to get google checkout to work for a few nights now and have finally given up and need help.
i have checked out the google help centre for this mod and also searched through this forum but unable to find an answer.
I have followed the instructions to the letter, modified all the correct files as per the instructions but when i go through google checkout proceedure (as a customer) it takes the sale fine but does not update zencart and clicking the back to website link it says "Whoops! Your session has expired."
i am currently running in sandbox in http mode - response handler is also http:/webaddress goes here/responsehandler.php
i have tried the various attempts using different settings to get this to work both https both http (settings and google checkout)
any help would be greatly appreciated
