Hello i upgrade to new version of Ispconfig(3.2.6) and i got in cron this error: WARNING - There is already a lockfile set, but no process running with this pid (3543). Continuing. PHP Fatal error: Call to undefined function array_column() in /usr/local/ispconfig/server/plugins-available/webserver_plugin.inc.php on line 111 And the change from ispconfig si not saving. The server was fine before upgrade.
You can try to use this workaround: https://git.ispconfig.org/ispconfig/ispconfig3/-/issues/6177#note_95892
