Problem: The client is unable to switch languages using the URL rewriting option in WPML. They receive an error message indicating that 'languages per directories will not function' due to potential issues with WordPress installation location, URL rewriting not being enabled on the web server, or the web server's inability to write to the .htaccess file.
Solution: We recommend the following steps to troubleshoot the issue: 1. Set the Language URL Format in WPML settings. 2. Visit the front end of your website to check if it displays correctly. - If the front end displays as expected, the error message is a false-positive, and you can continue using the URL Structure without any issues. - If you encounter an error 500, a blank page, or an error 503 on the front end, and it's resolved by changing the URL Structure, then further investigation is needed.
If this solution does not seem relevant to your situation, please open a new support ticket with us, and we'll be happy to assist you further.
