Permalinks are broken after migration

hello everyone,

I really hope to find help here because I dont know what to do.
After site migration from one domain to another, part of permalinks stopped working - they point to the Not Found Page. I could understand if they all stopped working, but only part of them - in the Events section: http://olivia.be/events/ by clicking on Read more of the Particular Event the link points to Not found page: http://olivia.be/event-view-nl/rotary-sint-truiden-organiseert-een-concert/
What happened? How can this be solved and where to look? Please?

 

Go to the dashboard - settings - permalinks - and click "save changes"

 

I did it already, it didnot help

 

So the particular pages that are not showing up, if you go to the edit page from the dashboard is the url the same ?

 

I think .htaccess is not writeable by that page please open the .htaccess and update the path in the file. You need to update the RewriteBase and RewriteRule

 

Make sure the rewrite engine is on in your .htaccess. I would also recommend another host, if you wan't one send me a private message. The site is too slow .
