This morning a customer placed an order without problem in our cart using the Square payment module. I just discovered that as of this afternoon, the Square payment method fields appear in step 2 of checkout but no text can be entered. Thus, customers are unable to place an order. Anyone experience this or have a clue where to look for a solution.
