Oh No, we can't find your Pledge

I get this message "Oh No, we can't find your Pledge. ..." on return from Live Paypal on thank you page.
- Wordpress Version: 3.5.1
- Fundrising Version : 2.2.4

I've set the IPN on Paypal and I can see the pledges in the admin and status of 200 in IPN History.

I need to see the thank you page and to trigger the email.

On PHP debug on wordpress I get:
