gk-speakers widget animation

The widget in the home page isn't switching the images, and it used to do it before, there's something that stopped it. There are more than 6 speakers in the category, everything seems t be OK, but I couldn't find the reason that it stopped for the past 2 days, and I really need help with that.

This is my home page:
