all is there,. nothing visible

alright,. I changed computer, put the harddrive in the new computer, boot up and everything is working fine, I can see the contents, comment, edit and save them. but only when I’m logged in.

But it doesn’t show when viewing the site.

look at http://www.irish-music.org/wordpress

it’s nothing wrong with the database.
what’s wrong?

glad for answers /kalle
