On the return page after paypal donation getting the message "Oh No, we can't find your Pledge" I waited and tried refreshing, same message.
I'm on a test server using paypal sandbox, but I get the same message from production. On the test server I have turned off all plugins and changed the theme to 2010 and deactivated buddypress.
On test server:
Running WordPress: 3.3.2
Theme: Twenty Ten
Thanks in advance for your help
