Issue Symptoms
I am trying to pay my subscription but I keep receiving the following error:
Our credit card processor encountered the following error: [51] Decline. Your credit card has not been charged.
Resolution Steps
The [51] Decline code error means that there are insufficient funds on your credit card to process the payment. To fix this issue, submit your payment using a different credit card or call your credit card issuer (the phone number is usually on the back of your card).
For more information about common error codes, see the article: Resolving issues when your credit card fails.
