oh no we can't find your payment message after payment is made.

Hi, I tested the fundraising plugin on a blank theme and it worked well. Now I am trying to integrate it with the Mission theme and having a few issues. The biggest is that when I make a donation, I return to the site and get this message:"Oh No, we can't find your Pledge. Sometimes it take a few moments for your Pledge to be logged. You can try refreshing this page" - this is a show-stopper. Hope you can help. thanks.
