Problem: You want to rename built-in language names in the WPML language switcher dropdown, such as changing 'Norwegian Bokmål' to 'Norwegian (no)' and 'Portuguese, Brazil' to 'Brazil (Pt)'. However, you encounter issues because there is no option to edit a language once added, and attempting to add a custom language with an existing language code results in an error. Solution: To change the default language names for the language switcher, follow these steps: 1. Activate the pre-configured language you want to rename by going to WPML → Languages. 2. Change its locale by editing the language and assigning it a new locale (e.g., en_EN or a custom value). 3. Save the changes. 4. Now, add your custom language using the now-free original locale. For more detailed instructions on adding custom languages, visit Adding Custom Languages.
