I think due to jquery updates in latter wordpress versions (now with 1.8.3), the slider within the Photoria theme (from wpzoom) is no longer working.
I have pages established with featured images and this was working, now with recent updates only the first image displays (others are pre-loaded and hidden by the css) but the auto/manual scrolling next/previous does not activate the change or show the other images.
In the console I can see an error;
Syntax error, unrecognized expression: [object Object][rel='2']
But can not find where this is activated or what to modify to correct the problem.
