conf generation HS when last servicegroup disabled

[dmagniez]

Hello,

In Centreon 21.10
when the last servicegroup is disabled, we can't generate configuration file anymore.

error thrown by PHP :

`==> /var/log/php-fpm/centreon-error.log <==
[13-Dec-2021 16:01:31 Europe/Paris] PHP Fatal error: Uncaught TypeError: count(): Argument #1 ($value) must be of type Countable|array, null given in /usr/share/centreon/www/class/config-generate/servicegroup.class.php:183

I'm facing the same issue except it doesn't look like it is limited to servicegroups. Instead, it seems to affect services as well.

We found the culprit ! A service inheriting from a disabled template had been created in the meantime.
Too bad that it doesn't pop up a clearer error message. In addition, except if i miss something, it should not be possible to select a disabled template when creating a new host/service/contact...

I'm facing this issue too after upgrading from 3.4 to latest. I removed all disabled services/hosts/servicesgroup etc but nothing helps to generate the conf file
