Problem: The client is facing two critical issues blocking their site launch: 1) The WPML language switcher fails on mobile and tablet views, not displaying other languages for switching, although it works correctly on desktop. 2) When switching languages on WooCommerce order view pages, the order ID parameter is lost, and users are redirected to the dashboard instead of the translated endpoint URL. Solution: We recommended the client to ensure a full site backup before proceeding with any changes. We then suggested reproducing the issue on a staging site with minimal environment settings to isolate the problem. If the issue disappears in a minimal environment, the client should reactivate other plugins one by one to identify the conflicting plugin. This step-by-step approach helps pinpoint the exact cause of the malfunction.
If this solution does not resolve your issue, or if it seems outdated or irrelevant to your case, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix,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 problems persist, please open a new support ticket at WPML support forum for further assistance.
