PTS stripe not display the card form

[s.elettronew]

Hi guys,

There is something strange in my checkout. I have 2 version of my web site. One is the original site, all working perfectly and then i have my website test version, where i have the problem on the checkout.

The problem is in the checkout, when i put all data and i want pay with cart, the litlle frame of PTS stripe, not show me the form for put the card data while in the original website that's working nice (these two are the same version and same files!)

I'm asking why? I reset the website 2 times, and i have the same problem
