Blog / news page error 404

Hey guys,

I get this error on my website.

It can’t find the news page. I have set up the WP blog system to view articles on the news page. But sometime within the last 5-6 weeks the page has stopped working. I have been doing a lot of work on the site, but i can’t seem to trace back to what have happened.. I am open to all suggestions you might have, as i am getting frustrated.

Yours sincerely Anders Jytzler
