Problems At Checkout With Buyshop Theme

Hello, I'm really hoping someone can help with this.

We have installed and designed a store for a client using the theme Buyshop. I believe this is quite a popular theme.

At the checkout though we are experiencing an error with the payment processor. The braintree inputs aren't showing and when you try to select another processor the loading wheel appears and doesn't disappear again.

The console shows the javascript errors attached and the site in question is here: https://wrightsport.co.uk/

I'm now having a hard time getting hold of the themes designers.

If there's anyone that could point me in the right direction so I can solve it without them that would be appreciated.

Buyshop theme demo is on CS-Cart 4.1.2 maybe its not even compatible with you 4.81
