• Debian 11 has reached its end-of-life (vendor EOL date - August 31, 2026). Plesk Obsidian 18.0.81 is 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.

Not able to edit default php settings

In order to edit these values, you must either be "Reseller" or the "admin" user of the server. Are you logged in as a reseller or as "admin"?

Another, not so popular option is to allow users to configure PHP settings in the service plan associated with a subscription. That however brings the risk that users also add "additional PHP directives" that you would not want to be used on your server. In that case you should also make sure that some important settings like disabling "exec", "shellexec" etc. functions are hard coded into the general PHP ini file of your PHP versions on your server so that users cannot remove the limits.
