My customers are getting the error message Unable to process payment when they enter their credit card details to make a purchase on my site, I would be very grateful if someone could help me fix this. 

Many thanks

This usually indicates an issue with your Stripe or PayPal connection.

To check this:

• Ensure your Stripe account is verified, or Contact Stripe directly to ensure your account is fully set up.
• Refresh your connection by disconnecting and reconnecting Stripe (keep in mind, this may interrupt your active subscriptions).
• If you use PayPal, disconnect and reconnect your account or contact PayPal directly.

If none of these fix your issue, I recommend that you contact Squarespace Customer Care. You can reach out to them here. At this time of day, they offer a live chat feature.
 

thanks so much, Paul, we'll give this a try Nicola
