Service proftp Won't Start -> fix = Line 8 of /etc/proftpd/conf.d/virtualmin.conf

Operating system CentOS Linux 7.6.1810 Kernel and CPU Linux 3.10.0-957.21.3.el7.x86_64 on x86_64 Webmin version 1.900 Virtualmin version 6.06

/etc/proftpd/conf.d/virtualmin.conf Line 8

TLSRSACertificateFile /etc/pki/tls/certs/proftpd.pem

Seams the file proftpd.pem is in another location and so I edited to this Line 8

TLSRSACertificateFile /etc/pki/tls/private/proftpd.pem #/etc/pki/tls/certs/proftpd.pem

Now proftpd will start as expected.

not sure if this is the correct fix or not - but if a BUG please fix.
