Hello,
Thank you for contacting Rank Math and sorry for any inconvenience that might have been caused due to that.
The WordPress team has informed the community that some deprecation notices might appear when using PHP8 or above and one of them is the ones you are currently seeing on your website.
Full details and explanation here: https://make.wordpress.org/core/2022/01/10/wordpress-5-9-and-php-8-0-8-1/
Unfortunately, there’s nothing we can do to prevent that as WordPress core is still not fully compatible with the latest versions of PHP.
Hope this helps clarify your doubts.
Don’t hesitate to get in touch if you have any other questions.
