Cause

The Grafana authentication methods have been modified via Plesk panel.ini file.

Resolution

1. Connect to the server over SSH.

2. Create a backup of the panel.ini file:

   # cp -a /usr/local/psa/admin/conf/panel.ini{,.bk}

3. Open /usr/local/psa/admin/conf/panel.ini in a text editor such as VI.

4. Delete the following two lines:

   [ext-grafana]
   allowSuperAdmin = true

5. Save the changes and close the file.
