checkout error with credit card

one of my stores in woocommerce began to issue a few days ago. At checkout with when a customer tries to pay with a credit card shows an error message: “Document number is missing”

The developer of the plugin did not issue it. The gateway support either.

Both said that the error is because of something on the site being unable to send the CPF (personal identification in Brazil) to the gateway at checkout.

As I have no idea what that is, I need to know if any of the plugins that you can use in any way be blocking this information to get to the checkout.

i use these plugins on this site:

WP Hummingbird

WP Defender

WP Smush Pro
