Everything seems to go fine until I try to start XAMPP. Then I get:
test-Dimension-8400 Downloads # sudo /opt/lampp/lampp start
Starting XAMPP for Linux 1.8.1...
XAMPP: Another web server daemon is already running.
XAMPP: XAMPP-MySQL is already running.
XAMPP: XAMPP-ProFTPD is already running.
XAMPP for Linux started.
Its seems like there may be another web server running? (I am new to Linux.....since yesterday. Just trying to get a developmental web server up and running.)

I noticed the other posts are a few years old. Is there somewhere else I should go for help on this?

Thanks
