Let us know how this goes.
Thank you.
I feel totally cheated and scammed. I paid $57.93 and they offer me a free plugin. After more than 10 days I am still the same and I have lost my money.
Hello,
We are really sorry for the confusion.
The Content AI Enable/Disable button is there in the Free Rank Math plugin but you’ll get the Content Credit for the AI search once you purchase the Content AI plan and with the credit you can use the Content AI feature.
After you purchase the Content AI starter plan, you need to enable the Content AI feature as mentioned above. Then please ensure that you have refreshed the credits in the Rank Math plugin settings. You can do this by navigating to WordPress Dashboard → Rank Math → General Settings → Content AI and refreshing the credits. Here’s a screenshot for reference:

Once you have refreshed the credits, you should be able to start using Content AI without any issues.
If you encounter any further difficulties, please feel free to let us know so we can assist you further.
Thank you.
