Issue has been noticed with proftpd when the server is upgraded to 4.1 on FC1. proftpd.conf.wp is changed when upgraded to 4.1.0 from 4.0.3.

This caused the failure of the proftpd service and the service is not started.

To fix the issue execute the attached script fix_proftpd.pl  and restart proftpd service.
a. perl fix_proftpd.pl
b. service proftpd restart
