Hello,
We apologize for the inconvenience you’re experiencing with using AI credits after purchasing Rank Math Pro from a third-party seller. It seems that there might be an issue with the activation of AI credits when using a Rank Math Pro version purchased from WP Pro For All.
To address this concern, we recommend that you first ensure that your Rank Math Pro version is indeed a legitimate purchase and that it is correctly activated. If the issue persists, please try disconnecting and reconnecting your Rank Math account as shown in the screenshot below:

After reconnecting your Rank Math account, please head over to your Content AI and refresh the credits count again so the plugin will request the updated credits from our server and display the correct count.
If the issue still persists after following these steps, please let us know, and we’ll be happy to assist you further.
Thank you for bringing this to our attention, and we appreciate your patience as we work to resolve this issue for you.
Looking forward to your response.

Hello,
I tried disconnect and reconnect account many times, and the problem still persists.
Tried again today(1/18), still fail.
Can anyone help? I appreciate it very much.
Hello,
Thank you for contacting support.
The credits can only be used when they are purchased from the same account that is used for the paid subscription.
If you would like to use credits, you need to ask the person who is offering the Business subscription to purchase them for you and allocate them to your website or purchase a PRO subscription on this account.
Since in the current state, it’s not possible to use the credits on this account we can offer a refund on them, if you wish.
Let us know how you want to proceed.
Thank you.
Hello Miguel,
Thanks for your reply.
I’ve used hundreds of credits, can I still get refund?
If so, please kindly assist with the refund.
I appreciate it in advance.

As requested, we have initiated a refund on your requested transaction. You should see a credit for the refund appear on your credit card statement anytime between now and the next 5 to 7 business days.
