[Solved] Apache directives not set with ISPConfig 3.1.2

hi all,
I'm used ISPConfig with many server.
I just update the panel to 3.1.2 (mysql) and add a new web server (that also used 3.1.2 with mariadb).
I have set correctly a new web site on it without any problems but the apache directives are not saved in the apache configuration file.
Another web server, that use 3.1 is perfectly working (with mysql)
The command "/usr/local/ispconfig/server/server.sh" report only "finished".
Thanks for help,
Yannick
Debian 8 update-to-date / apache 2.4 / php 5.6

 

Solved. The first apache directive was a header directive, and the module was not enabled in apache.
