Update Advanced Monitoring and Grafana to the latest version.

If update is not possible for some reason, as a workaround:

For Linux:

Connect to the server via SSH
Run the following command to downgrade grafana package:
RPM-based systems (CentOS, RHEL):
# yum downgrade grafana-7.5.7-1.x86_64

APT-based systems (Ubuntu, Debian):

# apt-get install grafana=7.5.5
Log in to Plesk
Go to Tools and Settings > System Updates > All Packages tab, find grafana using the search bar, select it and click Lock to prevent automatic update of the package:

Note: When bug is fixed revert this change

For Windows:

Connect to the server via RDP
Download the file grafana-1.2.2-228.zip.
```
Login: plesk
Password: VB3QnSjtZO5rtv1E
```
Log in to Plesk
Go to Extensions and install Panel.ini Editor extension
Go to Extensions > My Extensions > Panel.ini editor > Edit and add the following lines to allow installing extensions from zip archives:
```
[ext-catalog]
extensionUpload = true
```
