[Решено] Change Original Language for Automatic Translation.

Background of the issue:
I would like to use the automatic translation feature in WPML to translate content from English to other languages. My website was initially created in Arabic and later translated into English. The current default language of the site is English, but WPML still recognizes the original language of the pages as Arabic, with English marked as the translation.

Symptoms:
I am unable to use the automatic translation tool for English, as WPML displays an error stating: "You can only automatically translate content from your site’s default language (English) to your site’s other languages. Deselect content in your site’s secondary languages to proceed."

Questions:
How can I change the original language of my pages and posts to English so that I can use the automatic translation feature properly?
