In master site just i have renamed the installation directory like "__installation" before installing the multisite component.But after creating the multisite I can see the installation directory into that (master)folder but site is running,it's not showing the error message like
"Please remove your installation directory completely".

In slave site installation directory is available but configuration.php file is missing
While making the templates for slave site I have choose the "copy folder with subfolder links" for intallation directory as per the video tutorials.

How to resolve this kindly assist me.......

Once the Jms Multi Sites patches are installed, the "installation" directory is restored to allow creating new "fresh slaves" sites.
Jms Multi Sites is able to make the distinction between a "configuration.php" file that is not present and that require the "installation" directory or the case where the "installation" directory can be ignored.

We didn't changed the "Joomla Installer" to change its message.
When you clik to start the "site" or the "admin", when the patches are installed, it can be started immediately without removing the "installation" directory.

Do do not delete the "installation" directory that is present in the master as it is used when creating "fresh" slave sites to allow them lauching the "Joomla Installer"

Hi,

I need one clarification for multisite while creating the slave site,Where ever it will create the dir.

one is under under multisite dir as like [/var/www/html/master/multisite/slave1] and another one is [/var/www/html/slave1].

is it right?

Jms Multisites never create the directory except when you enable the check box that ask to create the deployed folder.

The "/multisites/{site_id}" is the location where JMS Multisite saves the definition of a slave site. So in this case, it already exists as it is created by JMS multisite to save its data. In most of the cases, I have used this directory in the sample to avoid creating a new directory.

I have created the slave site and installed it,whenever i click the slave site it goes to joomla installer screen and ask to install the site. What may be the issue kindly assit me to solve this issue.
