    Perfect server Debian Jessie build, v 8.10 ispc3 v3.1.13
    I am in the process of installing SSL on all the sites on this machine but I have come unstuck with the 1st.
    This accessible via http. ispC and phpMyAdmin and the mail system are using SSL ok. I have modified ssl.conf to disable SSLv2, TLS1 & TLS1.2 using the suggestions from Till's post. However Apache failed to restart because of the "SSLSessionTickets off" line. I disabled this and Apache restarted.
    I removed SSL and saved the site config in ispConfig then re-enabled and saved it again but still couldn't access the site with https.
    I checked the contents of "sites-available" and noticed that SSLv2, SSLv3, TLSv1 & TLSv1.2 were disabled!
    I edited the line to read "SSLProtocol All -SSLv2 -SSLv3 -TLSv1 -TLSv1.1" but still no luck.
    The <IfModule mod_ssl.c>code from ssl.conf and sites available is below.
    I did not understand the comments in ~/posts/369744 so maybe disabling "SSLSessionTickets off" was a bad idea!
    apachectl -V produced the following
    apachectl -V
    AH00526: Syntax error on line 89 of /etc/apache2/mods-enabled/ssl.conf:
    Invalid command 'SSLSessionTickets', perhaps misspelled or defined by a module not included in the server configuration
    Action '-V' failed.
    The Apache error log may have more information.
