Hello,
Thank you for contacting Rank Math, and sorry for any inconvenience caused.
You can check the content AI credits here:
https://rankmath.com/my-account/websites/
If the credits are not updated on your website, please go to WordPress dashboard > Rank Math dashboard > Help > Disconnect and Connect again with your Rank Math account.
Then, head over to Content AI and refresh the credits count so the plugin will request the updated credits from our server:

Hope that helps. Please don’t hesitate to let us know if you need our assistance with anything else.
I said not showing, I didn;t ask where to check
Hello,
Can you please confirm if you tried reconnecting your Rank Math account to the plugin as instructed by my colleague?
If the issue persists, we might need to take a closer look at the settings. Please edit the first post on this ticket and include your WordPress login in the designated Sensitive Data section.
Please do take a complete backup of your website before sharing the information with us.

It is completely secure and only our support staff has access to that section. If you want, you can use the below plugin to generate a temporary login URL to your website and share that with us instead:
https://wordpress.org/plugins/temporary-login-without-password/
You can use the above plugin in conjunction with the WP Security Audit Log to monitor what changes our staff might make on your website (if any):

We really look forward to helping you.
