GoCardless Oops Errors
Symptom
Clients attempting to create new mandates via the GoCardless payment gateway module may encounter an Invalid filename for redirect
error (an Oops
error).
Cause
The format for some data that GoCardless returns when creating a new mandate has been changed. This causes WHMCS's data integrity validation to fail.
Hotfix
We have created a hotfix for WHMCS 8.5.1 to accept the new GoCardless URL schema. You can download it at:
