404 page not found

I created a page.

When adding [nggalbum id=3 template=compact] *something goes wrong with thumbnail and border http://postimg.org/image/nhk13fl6p/ (how to fix this aswell)

However in both cases [nggalbum id=3 template=extend] or [nggalbum id=3 template=compact] when clicking on the thumbnail i get a 404 page not found.

Using Version 1.9.12
