Hello. Community's everyone, I am trying to develop a payment gateway for WHMCS, and when I test in my development&testing environment, I will see the below errors after I try to click "Payment Gateway" under "Setting".
"$sdk_sign_cert_pwd" is used to typed into the merchant signature certification password, which is requested by the payment gateway provider. And this parmsparameter has been defined on the "public function yourmodulename_config".
Can anyone give me any clues? Thank you all.
```
