Background of the issue:
We are developing a website and we need to update the Swedish language code and URLs from sv to se, pt-pt to pt, and da to dk. I see the language code can't be edited from the WPML admin under languages/edit languages.
Symptoms:
The language code can't be edited from the WPML admin under languages/edit languages.
Questions:
Is there an automated way to update all posts and pages and custom fields URLs to the new language setting?
