Problem:

The client is experiencing a 'Wrong API Key' error on the checkout page when using the WooCommerce Multicurrency Plugin with Stripe. Disabling the plugin resolves the Stripe issue but removes the desired multilanguage and multicurrency functionalities.

Solution:

We conducted several tests on the client's staging site after upgrading to the latest versions of the necessary plugins. The issue was resolved by re-saving the currency settings (Swiss Franc) from WooCommerce >> WooCommerce Multilingual >> Multicurrency. We recommend the client to check their staging site to confirm if everything is working as expected.

If this solution does not apply to your case, or if it seems outdated, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If issues persist, please open a new support ticket at WPML support forum.
