proftp does not start after Update 1.2.17->1.3.8 on Debian 7.11

  • today i performed an update from 1.2.17 to 1.3.8. it ended with
    'i-MSCP has been successfully installed/updated.'
    but proftpd did not start correctly. a service proftpd restart says


    Code
    1. root@vs /usr/local/src/imscp-1.3.8: service proftpd restart/etc/init.d/proftpd: Zeile 48: [: Argument erwartet.[ ok ] Stopping ftp server: proftpd.[....] Starting ftp server: proftpdvs proftpd[14304]: mod_tls/2.4.3: compiled using OpenSSL version 'OpenSSL 1.0.1e 11 Feb 2013' headers, but linked to OpenSSL version 'OpenSSL 1.0.1t 3 May 2016' libraryvs proftpd[14304]: mod_sftp/0.9.8: compiled using OpenSSL version 'OpenSSL 1.0.1e 11 Feb 2013' headers, but linked to OpenSSL version 'OpenSSL 1.0.1t 3 May 2016' library. ok


    My System is
    - Debian 7.11
    - in an OpenVZ container
    - i-mscp is now 1.3.8
    - proftp


    proftpd ssl-conf is



    excluding tls and sftp brings back proftp without ssl, but the following remains:
    root@vs /usr/local/src/imscp-1.3.8: service proftpd restart
    /etc/init.d/proftpd: Zeile 48: [: Argument erwartet.


    As a next step i planned to upgrade from wheezy to jessie, but not sure to proceed. would this solve my problem?


    best regards
