WordPress plugin Lightbox mess

As I recently upgraded from WP2.7 to the 2.8-branch, some issues could be expected.
A recurring issue concerns a plugin I’m using to display those lovely popups (lightbox) to display images without leaving the page. Long story short: it’s not working anymore.

I’m currently looking into a solid replacement, but so far no luck. You’ll have to do with the non-lightboxed images I guess. 🙂

NEW: I’ve added Slimbox to this site, to get the boxes back. Thanks EER!
