Hello
Thank you for contacting Rank Math and bringing your concern to our attention. I’m sorry for any inconvenience this issue may have caused you.
I hope you have taken all the necessary steps mentioned here: https://rankmath.com/kb/zero-search-traffic-error/. In case you missed a step, please follow the guide one more time.
As mentioned by you, you took all the steps, then please be advised that it takes some time to fetch all the data, but the stats should start to appear. If you are still seeing no stats, please navigate to WordPress dashboard > Tools > Scheduled Actions > Pending:
https://yourdomain.com/wp-admin/tools?page=action-scheduler&status=pending
Run the rank_math/analytics/data_fetch scheduled action and wait for the data fetch to complete.
If the data fetch does not work, we might need to take a closer look at the settings. Please edit the first post on this ticket and include your WordPress & FTP logins 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.
