• 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.

My web server was knocked offline when I tried to upgrade. Currently, in add/remove programs it shows v8.6 but the plesk name server is v9.4. I can't get the home page of the control panel top resolve to index.php3. The error reads:

Notice: Use of undefined constant SPN_PATHBAR - assumed 'SPN_PATHBAR' in C:\Program Files\SWsoft\Plesk\admin\plib\class.Pathbar.php on line 40

Warning: Cannot modify header information - headers already sent by (output started at C:\Program Files\SWsoft\Plesk\admin\plib\class.Pathbar.php:40) in C:\Program Files\SWsoft\Plesk\admin\plib\auth.php3 on line 502

I am looking for a way to either roll back to 8.6 or complete the upgrade to 9.0 without losing all my customers websites and email. It's bad enough that they are offline at the moment due to this.

Can anybody provide a clue as to what is going on?
