Today I have had a few customers report that they receive an error when they come back from making payment thru PayPal. The payment goes thru and the order is set as Pending Shipment. I receive payment and the order email confirmation. I was able to reproduce the error. Here is what the cart shows when the customer comes back to the cart.
"The following error occurred while attempting to process your transaction:
A complete common gateway interface request was not received by the online processor. The request was missing all required parameters."
As far as I know this started today. Any ideas?

Following this post as I have this same or similar problem about once every few days. My best guess after troubleshooting this for months is possibly a slow hosting server that occurs from time to time and the transaction times out before it completes?

@Thom: It sounds like IPN (instant payment notification) worked and the return from PayPal for the customer didn't contain order parameters. Make sure you didn't change anything recently on the PayPal side that overrides how PayPal is supposed to return customers to your site (the link/post back should contain order information and a status code).

I have not made any changes with the Paypal side. From personal experience with my PayPal account I know they have been having problems with their site revamping. I have had troubles capturing payments and receiving "Fatal Errors" when checking transactions so my guess it's a PayPal problem. I have added a note to "ecomrelay.php" to let the customer know that the order did go thru and to disregard the notice below.
I thought maybe it had something to do with the change to RSA-256 security.
Thanks for the help.
Best regards,
