Complete slider remains hidden

For two WordPress sites I use the Lite version of this plugin. Both are still in development stage.

In one of the sites (http://wordpress.fean58.nl) the slider is not visible eventhough it’s all there in the page source. The other (local) site works flawless.

I already tried deactivating all other plugins to check whether this is a conflict issue. It didn’t help.

Is there anyone else who has dealt with this problem?
