WorldPay - Callback Issue?

[vivekgajjar]

I have recently purchased the RBS WorldPay module, and am having issue with it. When I try and process a payment it goes through all the WP stages ok and then when it tries to redirect to our store the following message appear "The cart cannot be loaded, or an order has already been placed using this cart.". Having checked the order history the payment seems to have been accepted is this possibly a Callback issue? What would be the best solution? I have tried to contact Prestashop but they have failed to reply.

 

By the way I am using PS V1.5.4.1 your help is much appreciated.

 

After having given up on the WorldPay module developed by PrestaShop, decided to try another worldpay module by modulesmarket for less than half price (compared to PrestaShop developed version) on the PrestaShop addons site:

 

http://addons.presta...0-worldpay.html

 

This module is a lot more configurable and the level of support that I have received from the developer has been prompt and simply outstanding and will recommend this module to anyone who is looking for a fully functional worldpay module.

I have just installed the module too and can vouch for the excellent level of support. Would definitely recommend it.

Hi, were you able to find out the cause of the problem with the module?

I am in the process of trying to integrate the RBS WorldPay module from Prestashop and also getting the error message "The cart cannot be loaded, or an order has already been placed using this cart."  We are using WorldPay's Select Junior Service and I am hoping that someone out there has found a fix for this issue...

 

Thanks in anticipation

This could actually be an issue with your server. I am assuming your are hosting this on a shared server? Some hosting companies disable loop call back connections to the same server for security reasons and to save resources. 

 

Contact them and see if this is the issue, if it is, upgrade to VPS or a dedicated platform - or edit the module to use full paths rather than loops. 

 

Hope this helps!

Please let us know when you contact your Hosting provider and check for any php or apache error logs that can detail exactly what the error is during the transaction. This would help us understand the issue better. Thank you!
