Hello i finally make it work: the social network using jomsocial and kunena on the master site, the slave site with shared this 2 components but with different menus and templates.

I have one big problem. Sharing jomsocial and kunena bring both content/user and also configuration sharing. This cause me the problem to cannot change jomsocial and kunena templates on slave sites.

I got a different template on the slave site so i need a different template for kunena and jomsocial. Is there a way to do not share configuration/layout or a trick to do it easily?

When you decide to share the JomSocial and Kunena, effectivelly, this also share the configuration that is saved in a specific table of these extensions.

Concerning Kunena, they use the table "#__kunena_config".
Perhaps you could try create a physical configuration table instead of a link on the shared slave site.

Concerning JomSocial, the table seems to be the "#__community_config"

Becaurefull if you are modifying the DB definition manually with PHPMyAdmin.

can you help me to create these phisycal tables without breaking the jms configuration?

You have to drop the view and create a table based on the current reference defined in the view that you will drop.

This is possible with our billable support.
