Unable to send payments. "We weren't able to complete your payment at this time"

[c_210]

I'm getting the error message, "Sorry, we weren't able to complete your payment at this time. Please try again later."

I've tried on Safari, Chrome and Firefox. 

I also tried it on the iphone app and when I do that, it says, "Your payment was denied". Why?
