Worldpay.com http notifications - fix required(repost)

The problem is concerning http notifications, "your response to our servers after post authorisation is not updating our records". i.e after remotely post authorising our payments, the status of the orders on our website remain pre-authorised. (eventhough the action is completed on worldpay servers. The same is true for when we remotely issue refunds. This problem started after [login to view URL] had a major upgrade of its systems. ## Deliverables We have been intouch with their support dept and this is the response: "The remote administration responses have changed slightly, for further details of this change please refer to: [login to view URL] (enter your company ID) -->click on change summary --> click on Technical Search for "Remote post-processing via /wcc/authorise" I suspect that your remote authorisation script in not parsing the new response correctly and therefore not updating the status of your orders. When you run the remote authorisation script, have you checked the status of the order in our back office, has the status changed to captured or completed? If the order statuses are changing in back office, then the script is sending the correct data to us. But is not updating your site, this would suggets that your script is not parsing for the correct response. To investigate this issue further, we will need to see the responses that you are receiving from us. If you are not receiving any response then we will need to see what you are sending to us." I don't know how to supply them with the info they require. We need a coder to take this matter forward to resolve the problem. Here is the callback failure message response we are receiving: 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: ? ? ? ? ? Error reported: Callback to <[login to view URL]>: NOT OK, recevied HTTP status: 500 ? ? Server Reference: mm1imspsp1:callbackFailureEmail-30102:MerchReq-824 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 ([login to view URL] or [login to view URL]) 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. We hope this information will be of assistance. Please refer to the WorldPay Knowledgebase - <[login to view URL]> - or contact your local Technical Support team if you want help or advice about using the callback facility or about this particular callback failure.
