Hello,
We apologize for the issue you are facing with your Content AI subscription. It seems that there might be a couple of reasons why you are encountering this message.
-
Content AI Subscription is Not Active: Please ensure that your subscription is active. You can check this by going to the Content AI plans page to verify your subscription status.

-
Website is Not Connected to Rank Math: If you see a message saying, "Start using Content AI by connecting your RankMath.com Account," it indicates that your website may not be properly connected to your Rank Math account. To resolve this, click the Connect Now button in the prompt.

If you have checked both of these and are still experiencing issues, please refresh your credits by going to WordPress Dashboard → Rank Math → General Settings → Content AI and refresh the credits. Here’s a screenshot for reference:

Once you have done this, try using Content AI again, and it should work without any issues.
Thank you for raising this concern, and please let us know if you need further assistance!
