Dear Competitors
we have discovered a validation issue with credit card payments on the blokart worlds website.
It is possible that some competitors have not successfully entered when paying with their credit card.
If you have successfully paid by credit card you should have got an order received email (click here for a sample).
You should also appear on the registration lists:
You can also check your credit card statement to confirm if the payment went through.
We have improved the site this morning to mitigate this issue.
If your order was not received, please enter again. 
On placing the order, please check that all required billing fields are completed. If not you will get an error message on payment (example) and you will not be taken to the Order Received page.
Your credit card is only charged on transfer to the order received page.
We have created a help page here: 
We apologize for the inconvenience.
