I have suddenly started getting failed woo commerce payments (error: "Name 'Credit card / debit card' must be less than 255 chars") since yesterday. This only seems to affect Amelia bookings - products bought from the shop seem to process normally, so I don't know why or how that should be? It does seem to coincide with Wordpress update to 6.7.1 - maybe? The booking is created in Amelia with a payment of £0.00, and WooCommerce shows a transaction 'Pending Payment'. I'm really not sure what is going on here, except that this only seems to be happening with transactions for Amelia bookings.

Thank you, the issue is resolved for now - it seems there is a problem with a recent Woo Payments update, I have rolled back the plugin until a new version is available. FYI, this is the response from Woo:

Sorry that you're experiencing this issue. This may be related to a recent change we made to introduct a Test Mode badge that's having unintended consequences with a small set of plugins.
 
There are a few options that we could look at to see if that resolves the issue. The first is to try our newer modern version of checkout. This is a quick change but not all plugins are compatible, so there is a chance of fixing one problem and introducing another.
