Unable to see seats plan

Hi,

I created a show with month Calendar tool.
I created and uploaded with success the csv file to manage the seats.
If I click to ” See the Show”, I’m able to see the scene.

But when I add the show code in a new worpress page, the scene don’t appear.

I decided to make a test with wordpress clean installation. I had no plugins installed, I choosed twenty ten theme and I had the same problem.
The seats plan isn’t visible.

Please follow this demo link : https://www.booking.corsiquebec.com/?page_id=4

I have no error messages, nothing of this kind when I created the seats plan.
I don’t what can I do to fix it.

I need your help to resolve this problem ??

Thx in advance.
