Hi
I've installed the latest Google Checkout contribution and am testing with the Google sandbox. Vat and shipping etc work fine but the order is not returned to Oscommerce. When trying to access responsehandler.php in my browser the page just times out which I believe is the problem.
I think it could be a hosting problem but would like some advice. In the GC error logs it says "Invalid Merchant Id/Key Pair" but I've checked these and they are as Google tells me.
Any help would be appreciated.
Thanks
