hello everybody,

I dont know what happened but after site migration from one domain to another, part of my permalinks in one section (Events) stopped working!
http://olivia.be/events/

When I click "Read More" on any event I have this: http://olivia.be/event-view-nl/rotar...t-een-concert/ Page not found!

How can I find out what is wrong? Please help!!! I'm desperate....
