this original post appears to be from a while back, but i am getting the same errors on a clients site:An error was returned by the Payment Gateway when attempting to process the payment in background mode. Please forward this message to the webmaster. CHECKOUT_ERR_005.
the odd thing is this issue seems to be sporadic - as some orders go through and some do not.
the client is using paypal pro - and using Avactis 2.0.0
apparently after a user checks out, its like the page gets stuck and just spins....for maybe 5 minutes or more (sometimes infinitely)...and then returns the error above.
It is inconsistent w/browsers - as the issue seems to include IE, Safari, Firefox......so its not pinpointed to one particular browser/version.
I have checked all of the things that Alex suggested...API certificate....etc...........and as i said, some orders go through, and some do not.....
Any help would be greatly appreciated.
I'm no expert by any means on the PayPal payment module, but through trying to resolve some PayPal Pro issues myself, I do have one observation that may help shed a little light on the subject.
The error code CHECKOUT_ERR_005 appears to be "catch all" Avactis error code for any errors returned from PayPal in the final part of the transaction. It appears that PayPal may return an error code, error short message or error long message. If any of these things exist, then the PayPal module gets set to display what you are seeing.
This would explain why some orders go through and some don't. The ones that don't are returning some sort of error code/message, you just don't know what it is. Perhaps it's in your system logs?
