The plugin has been working perfectly for me for a long time. But as soon as I updated to 3.4, it stopped showing anything at all. I debugged it, and got the "is not a function" error. Downgraded to 3.3, and it works perfectly. I am not sure what the issue might be. Any ideas? I would love to go back to the new version but nothing shows.
