404 page not found after perlink changed

Hi,

because of seo reason I changed the permalink structure of my page. For the blog posts I added the slug /artikel/ in front of the blog post.

When I tested my site, klicking on the videos in All-in-one-video ended up in page not found.

The video is hosted on vimeo with access public. The access to the videos had functioned before.

Can you please help me

Thanks

Eva
