Php-fpm 7.0 not working

Hello,

We update to the last version of ispconfig 3.1.6 with debian 9 (following the doc).
PHP7.0 fastcgi works fine but fpm is not working.

When we create a site with fpm the file webXXX.conf isn't create.
In debug mode we see:
Writing the PHP-FPM config file: /etc/php5/fpm/pool.d/web1492.conf
But the new folder tree is : /etc/php/7.0/fpm/pool.d/...

On the same way, ispconfig try to restart php5 and not php7.0

To solve this problem, you have to edit your php setting (inside ispconfig)
Go to : Sytem -> Server Config -> Web -> Php Settings and adjust all paths

Auto detection during the install of ispconfig would be a good idea?
