I had to mark this plugin as broken, because the slide transition never worked for my setup and I was really forced to use the fade transition.
Now you have moved the fade transition to the Pro version. Therefor this plugin is no longer useful/working. And yes, I did try checking the "Disable Cycle2 Output" option and it still didn't work correctly. And yes, I already tried deregistering any other scripts that are not need on the same page as where the testimonial is/was being used.
