Form displaying Square Payment Error

My customers has sent me a screen shoot with this error message. Can you please advise me on how to fix it?

It seems that the Square account on your JotForm is disconnected which is likely to be causing the issue. Could you try connecting Square again from the payment wizard on your form so that it should be working fine? If it is displaying already connected, please try disconnecting and then connect it again.

Let us know if the issue still persists. We will be happy to take a look again.
