This thread is resolved. Here is a description of the problem and solution.
Problem:
The client reported issues with the language switcher on their website, where they often had to click twice on the French (FR) icon for it to switch languages, and sometimes it would revert back to English (EN) when navigating to another page.
Solution:
We recommended enabling the footer language switcher as a potential solution to improve the responsiveness and accuracy of language switching. Detailed guidance on setting up the language switcher can be found here: Language Switcher Options. Additionally, we suggested testing the language switcher functionality in different browsers to determine if the issue might be browser-related.
If this solution does not resolve the issue or seems irrelevant due to being outdated or not applicable to your case, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent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. Should further assistance be needed, please open a new support ticket at WPML Support Forum.
