links not working

hey, i use your plugin many time for offline migration but now i am putting one online and the links are not working anymore. i saved the permalinks multiple times but it is still not working. i can go in the wp-admin. when ik go thruw there to admin-pages and even thruw that i cant get to the pages thruw the slug-links. the url is http://denieuwekhl.nl/wordpressKHL/wordpress/
most are my shelf made links so they will go to a localhost but next to the people the titles are permalinks and arent working either. do you have a solution?
