Issue with theme and Intuit/Woo

Hello, I’m using this theme with Woocommerce and the Intuit Payments Gateway. When first added and tested orders were process without issue. I’m now getting an error reading Provided card type is invalid. Provided token is invalid which the author of the plugin states is an issue with js in theme blocking this. I’ve switched to other themes and default themes and have no issue placing orders. What would be a quick solution here? This is on a live site where we’ve just launched the payment section. Thanks!
