Please contact your system administrator and report this error. Code: I accept the risk set disable-plaintext 0 thats my c-client.cf any idea's how to fix it?

Take a look at the bootom of http://www.howtoforge.com/perfect_setup_debian_sarge_p4 . Afterwards, you'll have to make some changes for your users in ISPConfig so that ISPConfig rewrites the configuration files.
