paypal not accepting credit card payments

I have paypal linked to several of my entry forms and the credit cards are being denied. if they sign into Paypal and use it that way, it works. However, if they try to enter credit card information it says "credit card denied" . NOt sure if I have old links or need to upgrade payment system

My recommendation is to re-create the integrations or finish them, as I could see this error message in some of the forms.
