I have two sites with Tubepress Galleries and I just realized that the thumbnails have stopped working recently though I'm not sure why as they used to play just fine... The thumbnails still appear, but whenever you click on them nothing happens, i.e. the first video is always loaded in the top player no matter the gallery.

Any help or suggestions would be greatly appreciated, thank you!
