This thread is resolved. Here is a description of the problem and solution.
Problem:
The client's payment confirmation page is displaying a mix of French and English.
Solution:
We recommend updating all WPML plugins to their latest versions and then checking if the problem persists. If the issue remains, we advise creating a new staging site. On this staging site, use the default WordPress theme and enable only the WPML plugins and WooCommerce, while disabling all other plugins. This will help determine if the problem is related to a theme or plugin conflict.
If the problem continues after following these steps, we suggest visiting our known issues page to see if it's a documented problem. Also, ensure that you have the latest versions of your themes and plugins installed. If the solution provided here is not relevant to your case, either because it's outdated or not applicable, please don't hesitate to open a new support ticket with us for further assistance. You can do so by visiting our support forum.
