When someone goes to pay on my site through JotForm it does not accept the payment

Secondly, I realized the other day that when someone goes to pay on my site through jotform, it doesn't accept the payment- and says the link is broken. Can you tell me why this is?

As I check your account, it is currently holding Bronze subscription plan. Please note that the Bronze subscription plan has a limit of receiving up to 100 payments in a month. Your account has already received more than 450 payments for the current month which is why the payment forms are disabled. In order to receive any payment submissions, it is required to upgrade your account to the next plans available as per your requirement.

Thanks!
