Joomla! provides an easy-to-use graphical user interface that simplifies the management and publishing of large volumes of content including HTML, documents, and rich media. Joomla! is used by organisations of all sizes for Public Web sites, Intranets, and Extranets and is supported by a community of thousands of users.
You can check the write status of relevent folders by going to ''Help->System Info" and then in the sub-menu to "Directory Permissions". With the FTP Layer enabled even if all directories are red, Joomla! will operate smoothly.
NOTE: the FTP layer is not required on a Windows host/server.]]>
It is worth mentioning that this does not have a negative effect on migrated data from older sites. The new implementation is fully backward compatible.]]>
