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.
The FTP Layer allows file operations (such as installing Extensions or updating the main configuration file) without having to make all the folders and files writable. This has been an issue on Linux and other Unix based platforms in respect of file permissions. This makes the site admin's life a lot easier and increases security of the site.
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.
This is now implemented by inserting a Read more... tag (the button is located below the editor area) a dotted line appears in the edited text showing the split location for the Read more.... A new Plugin takes care of the rest.
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.
