Suggested Solution
Please verify all the possible actions:
- Do not connect to this URL directly, please use MetricsCube Connector instead.
- If you are using the Connector and still have this problem, please make sure that you have copied properly all the MetricsCube Connector files to your WHMCS instance. You may try to upload all the files again.
- If you have used Quick Installation Method to install the application, please try again with the Standard Installation Method.
