ProFTP not working after update to version 1.1.7

After this Upgrade to 1.1.7 - SSL Error RebuidCustomerFiles

ProFTP cannot start.

When i start proftpd follow message comes:

* Starting ftp server proftpd s1110 proftpd[2736]: mod_tls/2.4.3: compiled using OpenSSL version 'OpenSSL 1.0.0e 6 Sep 2011' headers, but linked to OpenSSL version 'OpenSSL 1.0.1 14 Mar 2012' library
s1110 proftpd[2736]: Fatal: TLSRSACertificateFile: '/etc/imscp/{HOST_NAME}.pem' does not exist on line 115 of '/etc/proftpd/proftpd.conf'

Problem is the hostname File (.pem) in the ProFTP config:

TLSRSACertificateFile /etc/imscp/{HOST_NAME}.pem # SSL certfile
TLSRSACertificateKeyFile /etc/imscp/{HOST_NAME}.pem # SSL keyfile

{HOST_NAME} on my server is "s1110" but the File name is the FQDN of my server.

All works perfect. Update without any Errors.

Thanks Nuxwin for your fast Support!
