I paid for the service and it shows nothing inside ?

Hello,

Thank you for contacting the support and sorry for any inconvenience that might have been caused due to that.

It seems like you purchased the plugin with some other email address.

Can you please search and forward a receipt from FastSpring.com so we can locate your account?

We need to see the order number that starts with RANKMATH2#####-####-#####

We really look forward to hearing back from you. Thank you.
