Hello @afreshup,
Thank you for your query and we are so sorry about the trouble this must have caused.
If you’re referring to the “upgrade” messages/alert in your WP dashboard, those will not show once you installed the PRO plugin.
However, if you close the alert and it always comeback when you reload the page, there must be a caching issue happening. Please close the alert again, clear your website and browser caches and go to Rank Math → Status & Tools → Database Tools and clear the transients.
If clearing the cache from the server doesn’t help, you can also try to clear the notifications directly from the database by setting the rank_math_notifications
option in the WordPress options table to be a:0:{}
.
Hope that helps.
