from wamp to online server

Hi, I have put my site online but experience difficulties now. Only the home page is showing, the other pages can not be found. When I login, I can see the text of every page, but the page itself is not showing. I tried to add a new page online ("test2"), but except from standing in the menu, that one is also not being found. The database I imported using WP Migrate DB plugin. The url is http://www.yogatherapie.be/
