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.
