• Halloween is coming! To celebrate the occasion, we dusted off a couple of old skins, and even created a brand new one (Pixel).
    To get into the festive spirit, install the Skins extension.
  • The new Python extension is now available. It allows customers to deploy and manage WSGI-based Python applications on their websites directly from Plesk.
  • The Plesk Mobile apps for iOS and Android and the Plesk Mobile Center extension have been deprecated, and are no longer available for new installations. In Plesk Obsidian 18.0.84, the Plesk Mobile Center extension will be removed from servers during the upgrade, and the Plesk Mobile apps will lose their server management features.
  • The Social Login extension has been deprecated and will be removed in Plesk Obsidian 18.0.84. After that, it will no longer be possible to log in to Plesk with a Google, Facebook, GitHub account, or with a passkey. Plesk usernames and passwords, as well as logging in with a WebPros Account, are not affected.

Hello everyone

Since the latest Windows 10 update from Tuesday "update kb5018410 (2022.10)" encrypted smtp no longer work on all our Plesk servers. Many customers have reported that all Outlook versions are affected. Only the Windows update kb5018410 is decisive. If the latest Windows Update kb5018410 is uninstalled, it works again. Do you also have this problem and do you have a solution for it? At the moment I can only tell the customer to deinstall or unencrypted SMTP

it affects all ports 25 587 465
