-
01
Back up WHMCS
Save both files and the database before installing or upgrading.
-
02

Licensing model
AngleModules products validate RSA-signed licence responses. The distributed module contains only the public verification key. Customers enter their licence key; the private signing key remains on the AngleModules licensing server.
Opening a support request
Include the product version, WHMCS version, PHP version, exact error message, reproduction steps and relevant redacted logs. Never send passwords, API tokens, private keys or complete licence keys.
