Flexslider suddenly doesn't work anymore

I created this website long time ago:
http://www.deoudeberg.be/

with this template:
http://www.ansonika.com/bed-and-breakfast/

When you scroll to ROOMS, normally the pictures are scrolling automatically, but they don’t.
When you click on a picture, they zoom to the foreground and normally there are arrows to scroll to the next pictures, but there are none.
It happens on BOTH websites, mine AND the template.

Hi,
If you don’t mind please provide your ftp, we will try to clear this issue.

Is there a way to provide it without the whole world seeing it?
