[Plugin: Donate Plus] HELP!!! Wall/Email not working!!

Hello,
The transaction goes through just fine but nothing is displayed on the wall and the donor does not receive the thank you email!

I made several unsuccessful attempts to tweak things but with no results!

Is there anyone willing to take a look at things for me? Please!
This is a project for a non-profit organization that helps our wounded soldiers …an awesome honorable cause! Please help!
