Cannot create accounts (account status is not ok)

[Numicus]

I de-installed winCP and reinstalled it again today, but when adding an account I see a red traffic-sign (round with a diagonal stripe) indicating that the account is not succesfully created. When I switch to the account I see in red:
XXXX's account status is not ok!

ispcp_daemon-stdout.log.1205268350
and
ispcp_daemon-stderr.log.1205268350
are empty.

When running /var/www/ispcp/engine/ispcp-rqst-mngr (in debug mode=1)
I get this:

Can anyone point me to the right direction?
