Hello,
Thank you for contacting Rank Math and sorry for any inconvenience that might have been caused due to that.
Is it possible that you left the WP Debug mode turned on? Please turn it offer to get rid of this notice.
It is not an error. It is just a notice that will go away after you turn the debug mode off in your wp-config.php file.
I hope that helps and please do not hesitate to let us know if you need our assistance with anything else.
