Urgent WIX Credit Card Payment Debugging

I need an experienced developer who can immediately address the issue with my WIX website.

Key Requirements:
- Debug the credit card payment issue: Despite being cleared by both WIX and STRIPE, the website keeps displaying the following error message when users attempt to make a payment.

"There was a problem with your payment
The payment method doesn't support the currency of the product or service. Try another payment method or contact the site to complete your purchase.
Return to Checkout"

- Expertise in WIX: You must have a deep understanding of WIX website functionality, especially in relation to payment gateways.
- Proven experience with STRIPE: Given that STRIPE is the payment processor here, experience with this payment gateway is a must.
- Immediate availability: I need this issue resolved urgently, so you must be able to start working on it right away.

Please include in your proposal:
- Your experience with similar issues on WIX websites
- Your familiarity with STRIPE's payment processes
- An estimate of how quickly you can resolve this issue
