- Plesk for Linux
A new task started in Plesk hangs (e.g. subscription creation, scan in WordPress Toolkit, update of extensions, etc.).
The following error message appears in the Plesk Task Manager log
CONFIG_TEXT: ERROR task=324 process=324 trace=7247:60da61c35a000 Start failed: Failed to start the process: exit status 1 (/usr/bin/systemd-run: unrecognized option '--quiet')
The server is running Debian OS which has been recently upgraded from Debian 8.
After some time, the following error can be found in
CONFIG_TEXT: ERR [panel] Argument 3 passed to Plesk\CommonPanel\Domain\Task\Create::isDnsEnabled() must be of the type array, null given, called in /opt/psa/admin/plib/CommonPanel/Domain/Task/Create.php on line 265:
