Using Elementor with Stripe-payments

I’m using your plugin and it works fine on my website :https://shop.mg-records.com/

I’m trying to use your plugin with Elementor plugin for a test-page but it doesn’t work.

I have contacted the Elementor developpers and sent your plugin file : they say they can’t do nothing.

Have you an idea of what is the problem ?

Thank you
Hoping it will help.
