Problem: The client is trying to change the currency from MXN to USD on the checkout page. They attempted to use custom code methods to update the currency cookie and filter the client currency, but neither method worked.
Solution: We recommend using the currency switch options provided by WooCommerce Multilingual, which are compatible with payment gateways like WooCommerce PayPal Payments, Stripe, and direct bank transfer. For more information, please refer to our documentation on multi-currency support in WooCommerce.
If the provided solution does not work because the payment gateway is not supported, the client may need to develop custom code to change the currency before checkout. We do not offer support for custom coding through our forum, but we have a network of third-party contractors who specialize in custom projects with WPML. You can find a list of them here: WPML Contractors.
Please note that the solution provided might be irrelevant if it's outdated or not applicable to your case. If this is the situation, we highly recommend checking related known issues at WPML Known Issues, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If you still need assistance, please open a new support ticket in our support forum.
