pure-ftpd login issue

One of our users when they try to login just sees a blank directory listing. No error messages are given and the permissions look okay for the directory. I replaced the username with USER for this purpose...

Is there a more specific pure-ftpd error log other than what is in messages?

/var/log/messages:
Jul 29 07:47:40 host pure-ftpd: (?@32.169.112.151) [INFO] USER is now logged in
Jul 29 07:47:48 host pure-ftpd: (USER@32.169.112.151) [INFO] Logout.

# ls -l /home | grep USER
drwx--x--x 19 USER USER 4096 Jul 29 07:46 USER/

# cat /etc/passwd | grep USER
USER:x:32038:32040::/home/USER:/usr/local/cpanel/bin/noshell


any ideas what could be the issue?

Thanks in advance.
