I guess they can't answer every question......
I solved this one ... Plain and simple....
I was running PHP5.... XOOPS does not run on PHP5 Aparently.
I'm now running PHP4 and installation went fine.
Or is the this files audio and video which does not start
because in this case a chmod 666 on the folder and files sql are advised
$gExtension = "wav mp3 mid mp3s";
