Problem: You have added Portuguese (Portugal) as a new language in WPML and want to change the slug from 'pt-pt' to 'pt'. However, you encountered an issue where the default locale had to be modified to 'pt_PTT', resulting in an incorrect
<html lang="pt-PTT">
attribute. Solution: To resolve this, you need to manually edit the database. Access the "wp_icl_languages" table in your database. Look for the entry corresponding to 'pt-pt' and change the Default Locale to your preferred setting. This adjustment will allow you to use 'pt' as the language code while maintaining the correct
<html lang="pt-PT">
attribute. Please be cautious and avoid making unnecessary changes to this or any other database tables as it can affect your site's functionality. For more details on WPML's database tables, visit WPML Tables Documentation.
