Finally I have given me time to do this the right way..not through fantastico.
I read through another similar post here and learned
What I did wrong is that I clicked on the entire demo folder and uploaded it to server.
Now the path to my installation is wrong, but works, but I want to get rid of the folder itself....
from support here in forum:
"this is how your folder tree should look like
after you transfer files to server
and so on
this would be wrong
I renemed the demo folder, but I like to get rid of the folder containing the demo..
do I have to delete it with everything in it and set this up folder by folder and file by file?
I'll wait with further actions until I get it right
