[Plugin: Lightbox 2] Lightbox not working on WP 2.5.1

Hi there,

I’m having issues with the lightbox-2 plugin on my WP installation. It’s not working at all :S

Here’s the error I’m getting:

element has no properties
fire(null, "dom:loaded", undefined)prototype.js (line 3936)
_methodized()prototype.js (line 247)
fireContentLoadedEvent()prototype.js (line 3969)
[Break on this error] element.dispatchEvent(event);

I’m using the last version of this plugin (v2.6.6). Can anyone help me out? This is my blog: https://rauru.com.

Thanks in advance!
