Copied:

As a possible workaround you can add a new section to the grafana configuration file /etc/grafana/grafana.ini

[plugins]

allow_loading_unsigned_plugins = grafana-simple-json-backend-datasource

and restart grafana server

# service grafana-server restart

On Windows the configuration file is here: C:\Program Files (x86)\Plesk\var\modules\grafana\grafana\conf\custom.ini
Grafana server on Windows/Unix also can be restarted via the command:

plesk ext grafana --grafana-restart

I know this issue was marked resolved but I have a similar issue. After removing Advanced Monitoring and Grafana extension from Plesk, I get the following log messages every couple seconds and the log keeps growing:
