WPML can automatically redirect visitors to their language, based on the browser's language setting.In order to allow visitors to later switch to a different language, this operation is done only once. WPML will set a cookie in the browser, indicating that the language has been set already and will not force the language on subsequent page loads.The browser language redirection runs in the visitor's browser, using Javascript. This allows for faster response and is robust to caching plugins that you can run on your site.If you are debugging browser language redirection on your site, please remember to check that:
- Your browser’s language is actually set
- You are testing in a new session
- No Javascript errors are happening
- Other plugins are not trying to redirect too
