Collapsing Extending doesn't work

I don’t know why but my Expand/Collapse has stopped working all of sudden and I haven’t even touched the FAQ plugin.

my site is http://www.clearkidneys.com/customer-support/

I’m using Chrome, but even in FF and IE, the expand/collapse feature doesn’t work. I use Thesis as a theme.

Also, whenever I click on one of the FAQs, an orange box appears around the Faq block. any idea?

Thanks
