Urgent help needed, please.

Hello,

Please provide more details regarding your Stripe Connect configuration and the nature of the error (where & when you got that "Unknown Error").

Regards,

At the payment page, where custoemr needs to complete card details. The message is right under card number text box appears after completing all card details. no more info or other messages. Data process is not even triggered as there is nothing on other end in Stripe admin panel.

Hello,

Some elements are still pending :

Please provide more details regarding your Stripe Connect configuration and the nature of the error (where & when you got that "Unknown Error").

If you have the credit card elements from Stripe, it means that the JS library is loaded ; but it also means that Stripe API is returning (in JavaScript) an error which is not currently handled by the plugin (so a generic error message is displayed).
Details of your configuration would still help ; and for the rest, it would need to analyse the content returned by the API ; and the way depends on how your plugin is configured.

Regards,
