Hi,

i'm receiving a 500 Server error most of the time with a basic integration of the paypal buttons - and therefore checkout.

Everything looks ok until this request (ordernumber is always different but not valid when it comes to a 500):

https://www.sandbox.paypal.com/webapps/hermes/api/order/*****/capture

It returns a 500 :

{"ack":"error","message":"Unhandled api error","meta":{"calc":"14a1a10ed47d3","rlog":"ypXqGXIrJLbuliO3bbBEWAdlN7trlfNi1o5Fq7nPVnA%2Bf1qHYgKE6Asd1fbHd%2Bex%2FIzqYptnS7aaaFdnAz%2BPiQ_16915871fa7"},"server":"1-P8TMckWiIkytlHVM2u4l4kYhEIbZJr0J6CSbkY03JF4VkBdPWL5JvihWIShgwJI-FS-q-YCh7eIFOERddRcfTrS_aJO1iRr3-vXGLyu7FPKs3BdvZ0muskcYG8iKgcw9O5rWP2WcMRa4dsd6lBdsp5mlDLA5W1qoxoEmbG3Jq6Ksi_hGhxJJr87Ivy9BQEFgbrLvC0SG3BeftpzgEHQWQRhDWAXD7MsuII5IQOXklKlxUF73gIRniVgNFB4NU4"}

Is there an issue with the sandbox or is there anything wrong with the implementation ? (which is unlikely since it's practically the sample code)
