I’m having the same issue. I didn’t upgrade; I just downloaded and installed the latest version of WooCommerce. Orders are not processing; they all get the following error message:
Error: “Please make sure your card details have been entered correctly and that your browser supports JavaScript.”
If I switch to the TwentyFifteen theme, the orders are processed successfully.
I’d love an ETA on when the theme will be updated. My album release is happening now, but I can’t sell anything!
Thanks,
Heather
