If you are already running this most recent version and still seeing problems, please try disabling your other plugins temporarily and switching to a default WordPress theme and test to see if your Shadow Box Buy Buttons work then. We have had a few reports of certain Themes causing issues with the Shadow Boxes and we are still working on tracking down the exact cause. If you do find that disabling your theme or a plugin works, please let us know which theme or plugin is causing the problem so that we can investigate the issue further.
