In case anyone’s having trouble locating this file, I found it here:
wp-content/plugins/nextgen-gallery/products/photocrati_nextgen/modules/lightbox/static/shutter
And the line that needed editing was 142. I’m using version 1.3.3 of shutter.js.
Whew, enabling jQuery worked. Thanks so much! That was driving me craaaaaazy.
I’m having the same problem! I’ve noticed another problem: hovering over menu items renders them invisible, as they are white text on a white background. The CSS refers to a .fadeThis span — I think this might be where that particular problem is. As far as the pleasant fading effect goes, I have no explanation for why that has stopped working. 🙁
