The message "No configuration file foundand no installatio code available" means that in the directory that is executed from your slave site, you don't have any "configuration.php" file or "/installation" directory to let the slave site starts the "Joomla Web Installer".
What I suggest is to start verifying the location where must be defined your slave site.
You can do that with the tutorial video 7 (hello.php) that you put in the root of your slave site directory.
When you are sure executing the
yourslave.com/hello.php
you will see the document root (or folder) where must be deployed the slave site.
Go in JMS and verify your "folder deployment " field to ensure that you have correctly defined the place where the slave site must be deployed.
Ensure that you have a "green (or blue)" message that tells you this is OK.
After that, when you have "no configuration.php" file, you must have the /installation directory that must be present in the slave site to let you runing the "Joomla Web Installer".
Also verify that you have installed the JMS patches that should restore the /installation directory in your master in case where you would deleted it.
A white page, as you can read plenty of time in the forum, is the syptom of a PHP fatal error.
To know the reason, you need to search for your "error_log" file or similar to get more info.
If you don't find any record in the "error_log", sometime, enable the Joomla debug mode may provide more info.
Also try to disable the "default language" to see if that would be related.
If yes, can you give us the Joomla version and JMS version that you are using to try reproducing it.
