breaks lightbox

hi,

i’m using quick cache & wp-jquery-lightbox (http://ww.wp.xz.cn/plugins/wp-jquery-lightbox/) but when activating your plugin the images won’t be displayed in lightbox anymore (tested with other lightbox plugins as well, to no avail)

is there a way to fix this, might be some kind of js-error?
