Cannot manage FTP-account or Domain by user account

Hi there,
I'm newbie in CWP. I'v installed CWP and it seem's work.
The problem is...
I created user account from root account.
At first time, I login to that account it seem's work correctly.
But a second time when I login, it looks like something wrong as a following picture




It looks like it cannot connect to a system correctly.
I cannot manage a domain or FTP account via this account I created.
It show the number of FTP account and Domain as NaN%, No add new domain button, No add new FTP account button.
Any suggestions?
Thank you.
