MCWHC001 - Error Code

Error Code: MCWHC001

The MetricsCube Connector cannot operate because the script cannot find WHMCS\Database\Capsule class.
It is a required class included by default in WHMCS since version 6.3. You are probably using an incompatible with MetricsCube version of WHMCS.

Suggested Solution

Please make sure that you are using WHMCS V6.3 or later to proceed.
