Configuration Function Errors

Problem

While attempting to process payment, the system returns the following error:

Gateway Module Error: Configuration Function (_config) not found

Cause

A payment gateway in the /modules/gateways folder is missing the required *_config function. WHMCS requires this function for successful use of the payment gateway.

Alternately, there may be unexpected non-gateway files in the /modules/gateways folder.

Solution

Audit your configured payment gateways to find the module and add the missing function.

For help to add this function to third-party payment gateway modules, contact the module developer.

If the issue is not a missing *_config function, find and remove the unexpected non-gateway files.
