Proftpd (No certificate files found!)
 

I have this problem, that everytime i try to start my proftp service, i get this in my console:

"No certificate files found!"

I have tryed to reset the /etc/proftpd.conf file, but it's the same!
i also have found this ducoment:

proftpd.or g/docs/faq/linked/faq-ch6.html

But i don't solve my problem!

How do i get proftpd uprunning again (google have no answers for us this time)?
