Setting up woopayments on our marketplace site

Double-check that WooPayments is correctly set up in your WooCommerce settings, and ensure all components—including WooCommerce, plugins, and the Xertio theme—are up to date.

If the issue persists when clicking to purchase, try switching to a default theme temporarily; this can help identify if the problem lies with the Xertio theme.
