Problem:
The client is experiencing an issue with a false activation notice for the WPML String Translation plugin, specifically related to Rank Math SEO settings.
Solution:
We have already contacted the Rank Math SEO plugin authors about this issue. Meanwhile, if you're experiencing this, we recommend following the workaround provided here: https://wpml.org/errata/rank-math-seo-false-string-translation-activation-notice/. Please ensure to back up your site before applying any changes.
The notice you see is a false positive and it's safe to ignore it for now. It will be addressed in a future update of the Rank Math SEO plugin. If you prefer not to wait, you may apply the workaround code yourself; otherwise, it's fine to leave it as is until an official fix is released.

Please note that this solution might be outdated or not applicable to your specific case. 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 the issue persists, please open a new support ticket.
