checkout error

Hi,

I was trying to use this stripe plug in for woocommerce and got the following error when I clicked check out:

Stripe checkout can’t communicate with our payment processor because the API key is invalid. Please contact the website owner or [email protected]

I was using the live mode with a live API from stripe. When I used the default stripe plugin in woocommerce, the payment can go through fine. Any idea what is causing this issue please?

Thank you.
