CWP create folder for subdomain with incorrect owner/group and permissions (if subfolder created outside /home/user/public_html)
1. Add a subdomain and assign for it directory outside main domain public_html, for example /home/user/subdomain/public_html
2. Check owner/group and directory mode from shell or from File Manager
#cd /home/user
#ls -l
drwxr-xr-x 3 root root 4096 Sep 26 09:51 subdomain
drwxr-x--- 5 user nobody 4096 Jan 9 2018 public_html
#
subdomain folder have root as owner:group and directory mode is 755 against 750 for main domain
I fixed this using root shell, but this is a bug for user.
