Flipbok Stoped working

Hi there,

Me bothering again. I couldn’t get the dropdowns to work. So I tested offline with a different theme and they worked fine. So I replaced the theme and now the dropdowns work just fine. But the flip book doesn’t show any more. “under tours”

I can browse to it by using the actual URL

http://www.caribbeantaxi.net/?flip_pong=bailando-cubano-total

but the link won’t show on the actual dropdown or anywhere on my site. I did check that the permanent links are set to default this time. But still no luck. Could you help me with this?

thank you
