I installed this plug in and it worked great... until I ran into a bug where it would only retrieve the 10 most recent transactions. I was desperate to find a solution. I understood the code, but I just couldn't find it. I thought maybe it was the date... no that wasn't it. Maybe it's PayPal. Maybe it's the international transaction I had.... what the heck is it?
Well I emailed Loki, the developer, and we worked together to find the problem. (He emailed me back within minutes!) We found the problem and voila! This plug in (2 versions later) really does it's job. It's amazing. Easy to implement and easy to style the progress bar to your own liking. I highly recommend it. Two thumbs up!
