Its activated and worlpay say that the callback is working but osc is not returning the response page...:(
I have asked worldpay and here is ther response...
Since i'm not a programmer hard to know for me what the problem is...
I see no error in my server log etc.. So i may think thats someting whit the worldpay module ?
Is worldpay 4 module work (or any other) on the latest osc may be i can try it ?
So i'm still stuck...
I can confirm that the callback process was completed successfully for both transactions.
Once a transaction has been successfully processed via WorldPay we can send an HTTP request (i.e. a communication) back to your shopping cart to advise on the outcome of this transaction. This mechanism is called payment response (formally called callback) and it has to be enabled on your account, from the "Integration Setup" page of your Select Junior Installation, from the Merchant Administration Interface (MAI) at http://www.worldpay.com/admin.
Payment response (i.e. callback) is a mechanism that WorldPay will use to send an HTTP query string back to your shopping cart/ website. The HTTP query string contains information pertaining to either a successful or cancelled transaction event. The payment response URL (as specified in the "Integration Setup" of your WorldPay installation) is the location of a script that interpret the HTTP query string from WorldPay, with the aim to performing a further action, for example updating an orders database. So for example the callback URL would be http://www.myserver.com/callback.asp.
Since you are using oSCommerce your shopping cart should use the shopper response mechanism to send a page of HTML to WorldPay, which should contain a link to allow the shopper to return to the originating website. Looking at our server logs your shopping cart is not providing us with a response page, and as such I would recommend that you look into why your shopping cart is not sending this response to WorldPay.
If I can be of any further help or assistance, on this or any other matters, please do not hesitate to contact me.
