The reward you chose is no longer available.

I just started running donation tests and I’ve hit an error. When attempting to make a donation on a project with no rewards offered, I get the following error:

The reward you chose is no longer available.

I then disabled the rewards system completely, and still got the same error.

I did some research and found this post from last October about the same issue that said it was fixed.

Please advise. I just purchased the fundingpress theme a couple of weeks ago, so I assume I have the latest version.
