Google Checkout integration problems

[modern_muffin]

I'm experiencing an issue with Google Checkout integration that I'm having trouble solving. Specifically, Google Checkout is indicating that there is an issue integrating with the E-Junkie cart and returning the following error for all orders where the customer selects Google Checkout as their checkout option:



We encountered an error trying to access your server at https://www.e-junkie.com/gc/196970/ResponseHandler.php -- the error we got is Send failed with code: 500. (Google Checkout then provides a copy of the XML that it tried sending to the E-Junkie URL.)



I've double and triple-checked the instructions provided by E-Junkie but am stilling having this problem. Any solutions?

The usual causes of that error are either incorrect GC Integration settings, or it can also happen if you receive any payments via GC that were not initiated from E-junkie purchase buttons.



Our required Google Checkout integration settings will have them attempt to inform our system of every payment you receive through their checkout process. If you are receiving any Google Checkout payments that were not initiated from E-junkie Cart or Buy Now buttons (e.g., if you use the "Send An Invoice" function in your Google Checkout account to request a payment manually), GC would still dutifully try to notify our system about those payments; however, our system would refuse to process an order that was not placed through our system to begin with, generating this error at GC's end that you can simply ignore.
