How do I reactivate Rank Math PRO??
I only wanted the AI cancelled from a couple of weeks ago but not the Rank Math PRO.
Hello,
Thank you so much for getting in touch.
Sorry, but we can’t re-activate the PRO subscription for you since it’s already expired and canceled.
You’ll have to purchase a new plan from here: https://rankmath.com/pricing/
Don’t worry, all your SEO settings will remain after purchasing a new plan.
Hope that helps.
