Problem: The client is experiencing issues with setting the language slug for Britain to /uk instead of en-GB. Solution: We recommend activating Ukrainian in WPML → Languages. Then, edit the Ukrainian language, changing the language name, locale, and other settings to English. If a warning appears about the English locale being in use, edit the English language to change its default locale to free up the English locale. This allows you to assign it to another language. Since the language code 'uk' is pre-configured for Ukrainian and cannot be changed, this method is necessary. For detailed steps, please visit Editing WPML's Languages Table.
If this solution does not apply to your case, or if it seems outdated, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If issues persist, please open a new support ticket.
