Hello,
Thank you for contacting Rank Math, and sorry for any inconvenience caused.
Please ensure that your payment method supports the following:
– Payments in USD $
– Supports subscription-based payments
– You are not using a prepaid card
– International payments are turned on
If everything from the above is enabled and working, you can also try using a different credit card instead.
Also, if you are using a Proxy or VPN, please disable that and use your actual ISP to make the purchase.
You can also call your bank and ask what’s stopping the payment to go through and request them to approve it on your end.
Looking forward to helping you.
I tried 2 cards, paypal and amazon, the error comes up before it even tries to process the payment. It’s not an issue with my payment method. Paypal or amazon don’t even open up to complete payment, the error come up as soon as I click on place order.
