 * Hi [@tavousi](https://wordpress.org/support/users/tavousi/),
 * Thank you for reaching out.
 * We were not able to replicate the warning in a local environment ourselves. We
   would like to know a bit more information.
 * Are all of your themes and plugins up to date? If not, can you please check if
   the warning persists after updating? If it does, we would encourage you to do
   a conflict check to see if the warning is there when Yoast SEO is the only active
   plugin or if you using a default theme such as TwentyTwenty. You can do this 
   with the troubleshooting mode that the Health Check plugin offers. Can you please
   do a conflict check as described [here](https://kb.yoast.com/kb/how-to-check-for-plugin-conflicts/)
   and let us know what you find? Thank you!
