When I try a test payment with events
I get the notification in Ogone that I paid.

But when I return to my site, I get the message:
"
Failure: Could not find payment processor for contribution record:
Failure: new order data not valid
Warning: Cannot modify header information - headers already sent by (output started at OgoneIPN.php:254) in /sites/all/modules/civicrm/CRM/Utils/System.php on line 333
"

I figured out that BaseIPN.php doesn't get the variables needed. Event ID is empty.
Can't figure out where it goes wrong do. I think the $ids array isn't filled, but why?

Warning: require_once(OgoneIPN.php) [function.require-once]: failed to open stream: 
No such file or directory in /path/to/civicrm/extern/OgoneNotify.php on line 12

I believe this should be fixed by something like https://github.com/GiantRobot/CiviCRM-Ogone-Payment-Processor/commit/0abe532e553fa570a4b04a87a4e1645498727246

After receiving Ogone response on OgoneNotify.php I end up on a blank page. If I reload this page I'm correctly redirected to the payment "thank you" page.

Any ideas why ?
