3.18 issue with Cybersource blank screen on event registration instead of 'thank you' page. Not a problem in 3.17

[Stoob]

Had an interesting issue where payments using Cybersource were going through, yet the registration 'thank you' for events never showed up. Instead the blank screen with IPN was all we say (see below) Rolled back to 3.17 and the problem went away.

Found this error in the logs.

That's frustrating because the error message is truncated :-(

[Stoob]

One could say that about almost all Civi error messages, couldn't one? ;-)

You might get more info replaying the notification through the api - although I suspect you probably just want to sit on the rolled back version for a bit

Yep we're doing version 3.17 just fine for now.
