What is the FTP layer for? PDF Print E-mail
Written by Administrator   
Friday, 06 October 2006 15:27

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.

    All daily sunspot numbers this week were 97 or less.

    Perhaps this indicates a move off of solar maximum, or to a future
    with a second maximum.

    Solar activity was way...

  • The K7RA Solar Update

    Average daily sunspot number plummeted to 104.4.

    Weekly Commentary on the Sun, the Magnetosphere, and the Earth's Ionosphere for December 12, 2024 from OK1HH:

    "The high solar activity in October this year suggests that this may have been the peak of an 11-year cycle.  This is not to say that solar activity will not continue to rise.  On the contrary, it may well be that the first maximum of the...
