Problem:
The website encountered a 404 error when attempting to change languages from the homepage, but internal pages were unaffected after migration to a new server. The issue seemed related to WPML despite checking other configurations.
Solution:
Initial troubleshooting steps included checking the website's URLs in "Settings -> General," increasing the WordPress memory limit, and reviewing PHP parameters. Eventually, the supporter discovered language directories in the site's root causing the problem and added "old" suffixes to resolve the issue.
