[Plugin – Simple Lightbox] nothing happens

I’m new to WP, I’ve installed SLB on my blog but nothing happens, clicking a picture still gets me to the picture itself instead of opening a lightbox. I’ve checked and the light box is enabled, I also set the url link when inserting the picture.

I’ve also read this topic:
