Worldpay Callback failure

[darrels]

Hi,
I have just setup the worldpay module on to our shopping cart at www.mdfdisplays.co.uk , all seems ok and it goes through to the worldpay payment page and the test transaction goes through. The problem i have is i keep getting a callback failure alert and once the worldpay payment has been made it does not direct you back to the main site. i have the callback set to :
http://<wpdisplay item="MC_callback"> and the correct boxes ticked, but it still fails to work.


This is the log that i get back from worldpay:

Our systems have detected that your callback has failed.

This callback failure means we were unable to pass information to your server about the following transaction:

Transaction ID: 289641272
Cart ID: dc223e2c0e0ebb4f241d0ed2bbee920c
Installation ID: 151874

Error reported: Callback to http://mdfdisplays.co.uk/shop/index....d0ed2bbee920c: NOT OK, recevied HTTP status: 301
Server Reference: mggaeq3a:callbackFailureEmail-3640388:MerchReq-981

Also, if you usually return a response page for us to display to the Shopper within the time allowed (1 minute), this will not have been displayed.

WorldPay will have displayed to the Shopper the response page file (resultY.html or resultC.html) held for your installation on the WorldPay server. This will be your own custom version, if you have supplied one, or, if not, the WorldPay default version.


Please help, what am i doing wrong ?

This is a response i got from Worldpay, but i dont understand what i need to do to resolve the issue. Can anyone help please ?

The reason why the callback process is failing is because your server is attempting to redirect the HTTP request from WorldPay to another URL, since the resource (i.e. wpcallback.html) at "http://mdfdisplays.co.uk/shop/wpcallback.html?installation=151874&zenid=b91c2cdddf01d935f72eac915383f21e&msgTy pe=authResult" has moved. Therefore please ensure that your shopping cart is sending the correct callback URL to WorldPay, or that the resource is located in correct location.

we moved from one server to another last night and have a tonne of missed callbacks.

Is there any way to tell zen that an order has been paid - or to force the callback???

This is quite urgent - any help would be great.

had this issue recently with OScommerce.
Callback failed with "The maximum limit of 131072 bytes has been exceeded"

turned out its to do with the size of the page being returned in the process.
Lots of new categories had been added and the javascript menu for products
had grown so the page had gone over 130k in size.

Made a custom header.php file for the pages involved in the callback and
this sorted it.
Presume same fix could be applied here.

Hope this helps others.
