Sorry i am looking for the way or step to install more then one site.
I read in the forum servels posted messages but i am not exactly understand how can i install 2 or 3 sites in one installation.
Has onybody the steps that i have to go?
You don't have to copy any folder in var/ but you need to create a new siteaccess in settings/siteaccess. All the configuration will be held there. Have a look on the doc and the forum, i think this has been already discussed.
