Views Slideshow output images as unformatted

I selected slideshow style for the view but my images still shown as if they are unformatted. Same problem with grid style. What should I do next to figure out what's wrong?

Images to the views comes from an imagefield in a node through imagecache.

I'm using VIews 6.x-2.12, Views Slideshow 6.x-2.3, Imagefield 6.x-3.10 and imagecache 6.x-2.0-beta10
