Promotional products do not load

Hi, see page here. www.facebook.com/pages/Play-Guitar-Singa...=app_214674098564273
When I click a link on the iRig - it's supposed to take me to the product page (shopping cart based on ajax)
Instead it goes to this link : www.play-guitar.sg/index.php/store#ecwid...jfbcCanvasBreakout=1
which doesn't work!
I think the https has something to do with it since it's being crossed out in my browser whereas if I access the store normally from my web page it's not being crossed out and it works...

Help!

Thanks.

Pier.

Nevermind, I use the app's link instead and it works.
apps.facebook.com/ecwid-shop/store/17762...id%3Aproduct=5887299
strange that I can't link out to a https website though..
