Cannot display the XAMPP homepage

[tosca30]

Hi,

Just coming from Windows/Wampserver, I'm now trying to run XAMPP with Linux/Ubuntu.
I went through the XAMPP installation procedure but cannot go further:
- http://localhost only displays the splash.php page, and the various languages links don't seem to work
- my own website homepage (the one that worked previously in Windows/Wampserver) returns a 403 error.

Thank you for helping.
