• If SSL/TLS support for a website is turned off, the “Open website” button now opens the website via HTTP. Plesk administrators can also set up “Open website” to open websites always via HTTP (regardless of website’s SSL/TLS support) by adding the following lines to the panel.ini file:

  [domainManagement]
  openButtonForceHttp = 1

  At the moment, the notification pane shows only one notification type (when one of the parameters monitored by Server Health reached the “red” alert level). More notifications are on the way.

If you renamed your domain or restored it from a backup and now face issues with your mail for a domain, assign an SSL/TLS certificate to the mail once again. (PPPM-10715)
• In File Manager, all files can no longer be renamed so that their names contain spaces at the beginning or end (for example, “file “ and “ file”). Previously, if the.htaccess file was renamed this way, a website could work incorrectly. (PPP-43006)

  Advanced Monitoring is a revamped version of the Server Health Monitor component, which inherits all the component’s features: detailed reports on the server health, on system resources’ usage, and so on. However, Advanced Monitoring displays all server metrics as visually appealing graphs and dashboards by Grafana.

  It is possible because Advanced Monitoring works in tandem with Grafana. When you install Advanced Monitoring, Grafana is also automatically installed. If you are an experienced Grafana user, server metrics collected by Advanced Monitoring is not your single source of data. You can also integrate Grafana with other data sources of your choice.

  For more information, read the descriptions of the Advanced Monitoring and Grafana extensions in the Extensions Catalog.
