Hello,
Thank you for contacting the support, and sorry for any inconvenience that might have been caused due to that.
Please head over to your WordPress admin area > Rank Math > Dashboard > Help, disconnect and reconnect your Rank Math account again.
If the plugin hasn’t been connected yet, you can simply just click on the “Connect” button.
After doing so, the domain should be listed on your rankmath.com account page.
Let us know how that goes. Looking forward to helping you.
Hello,
Since we did not hear back from you for 15 days, we are assuming that you found the solution. We are closing this support ticket.
If you still need assistance or any other help, please feel free to open a new support ticket, and we will be more than happy to assist.
Thank you.
