[Plugin: Testimonials Widget] Testimonials just not rotating?

Hi there,

Sorry to bother you, I know you have had a few of these. But the testimonials on the homepage of this site just aren’t rotating?

I’m not sure where we are going wrong with this one. Have used your great plugin loads of times but this one sticks. They only change upon page refresh, not in page.

Any suggestions would be great.

Thanks

Liam
