Can't delete user (sub-reseller)

[meh]

Hi,
I wonder why I can't select and delete users (resellers) in my kloxo panel?
I log in with main administrator account, but the option to select a client and delete him is disabled!!
any idea why and how can i completely remove a client from my kloxo Mr panel?

thanks

Somtimes i met that situation.

In that case, i tried to remove a user in kloxo db by phpmyadmin.
