It looks like you might be experiencing a known issue. Please try the workaround provided on this page: https://wpml.org/errata/flux-checkout-fatal-error-uncaught-valueerror-unknown-format-specifier-t/ Even if you’re not using the exact plugin mentioned, a similar issue can be triggered by other plugins registering a text domain incorrectly.
