Hey there @Amahani
Most CMS programs are PHP based and require a database in addition to the site files and core files of the installation. You will need to consult the user documentation for the CMS you're using or hire a developer that knows that particular CMS to help you out.
There might be someone on the forum that can help with that one. I've never heard of it, however.
