Problem:
You are building a multilingual website using WPML and Yoast SEO. Everything works fine for posts in the site's default language (Portuguese), but for translated posts (e.g., English), Yoast SEO fails to detect transition words and other readability checks, despite the WPML SEO plugin being installed and active.
Solution:
We recommend checking the profile screen of each user (Users -> Profile) and ensuring that the option 'Set admin language as editing language' is selected. This setting should resolve the issue as the admin language will then always match the language of the post being edited. Additionally, we have published an erratum regarding this issue, which you can find here: https://wpml.org/errata/yoast-seo-readability-analysis-can-provide-false-positives-when-your-display-language-does-not-match-the-post-language/.

If this solution does not apply to your case, or if it seems outdated, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have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 at our support forum.
