Like the other thread it says I have [charset] => windows-1252 but like the other poster I haven't changed anything in the site. Could that be the problem? I had a look on the Paypal dev site you linked to, but couldn't see anything about encoding on there. The end of the log file shows: Code: HTTP/1.0 302 Found Location: https://www.sandbox.paypal.com Server: BigIP Connection: close Content-Length: 0 invalid response Is there a way I can send you the full log file as I don't really want to post it on a public thread as this is?

Turn off the "send order details" option of the HikaShop plugin and try again to see if that helps. If not, try on a live account instead of the sandbox. You can still refund the order (and use a €1 product for your test) at no cost. I've seen cases where the issue was actually the sandbox account itself which had an issue. If that still doesn't help, it would be great that you contact the PayPal technical support and provide them with the payment log that you gave us so that they can check on their end what is the problem exactly.

We have now found the cause of the problem and it was caused by missing off the 's' in the https for the Paypal Sandbox URL. Easily missed, but obviously critical!
