Woocommerce lightbox has stopped working in my web http://www.justinyou.com
I have a problem with "Enable lightbox" checkbox in Woocommerce. It's impossible to get the checkbox ticked.
So the lightbox of woocommerce does not work and the product images open in a new window. The prev and next arrows dissapeared and now I have only an image whith the zoom symbol, but I cannot change to the next or previous one without going back in the page.
I had prove deactivating plugins and changing the theme (Mystile) to see if there was a conflict but it does not work.
Could you help me or give me an idea to find a solution?
Thanks in advance.
