• Debian 11 is approaching its end-of-life (vendor EOL date - August 31, 2026). Plesk Obsidian 18.0.80 will be the last release to support it.
    If you are running Plesk Obsidian on Debian 11, we recommend you upgrade those servers to Debian 12 using our dist-upgrade tool.
  • We plan to deprecate and remove the support for XML RPC protocol versions earlier than 1.6.9.1 in Plesk Obsidian 18.0.82. We strongly recommend that you update all existing integrations using earlier versions of the XML RPC protocol to comply with the version 1.6.9.1 specification.

Question PHP WARNING after update 8.027

There's nothing really wrong. It is just a warning that a constant is already defined when another script tries to define it again. It could be that plugins or the theme you are using are not yet perfectly compatible with PHP 8. It is best to look for an update of your plugins or themes or ask the manufacturer of your plugin(s) and theme.
