I have actually the version 30.0.1 but this errors did occur with the 29.0.x.
The complete message is: session_start(): ps_files_cleanup_dir: opendir(/tmp/.priv) failed: Permission denied (13) at /…/htdocs/nextcloud/lib/private/Session/Internal.php#198
the /tmp/.priv dir has the permission 733 for root.root
I cannot change the permission because it runs on a hosted server.
My question is: can i change the path to this directory?
Thanks for help
