I am using Client-side Express Checkout on my website, and it seems to have stopped working in the last day or so... a customer is able to pay by logging in as a PayPal account holder, but if they try and pay with credit card as a guest, it fails. If I do a console.log of err, it says 'forbidden'. Has something changed? I have seen some PP documentation that implies that they no longer support guest payments? I'm in the UK.
