Hi there I hope someone can help me. I need to create exact copies of the main site. My client runs a Wellbeing communications website and provides a website for each of their clients with relevant articles etc.

I have now followed every single tutorial and cannot get the slave site to duplicate the master site with its content. the only difference between the slave sites and master site will be the template.

any help ?

If you have everything in your master website and that you want to replicate all its content, watch the tutorial video 0.d moreless at 19:40 where it is explained how to replicate the master (rule replicMaster)
www.jms2win.com/en/tutorial#jms12x-0d

The key element is to select the "template site" = <master DB> and after specify the new DB parameters like (new table prefix, ...)

Once you have the rule that defined the processing, you can use it to create the slave site.
