Problem: The client is developing a site in three languages (Italian, English, and French) with Italian set as the main language in WPML. However, WordPress recognizes English as the main system language, affecting both the admin and frontend language settings. Solution: We recommend taking a backup of your site first. Then, navigate to Users>>Profile in your WordPress dashboard and set Italian as the language for Language. After this, clear all types of caches to ensure the changes take effect. It's important to note that the frontend language and dashboard language settings are different. For more detailed guidance, please refer to our documentation on setting the WordPress administration language: Setting the WordPress Administration Language.
