Apache Friends Support Forum

Hello all, sorry for my english

I have just install XAMPP and when i want to run it with the common command line "/opt/lampp/lampp start"
Here is what the terminal show :

> sudo /opt/lampp/lampp start
Starting XAMPP for Linux 7.1.8-0...
XAMPP: Starting Apache...fail.
XAMPP: Another web server is already running.
XAMPP: Starting MySQL...ok.
XAMPP: Starting ProFTPD...fail.
XAMPP: Another FTP daemon is already running.

Why FTP and Apache fail ? I have never installed the web server before this one

Thanks for the help
