woo commerce light box not working

Any Genius can help me with the light box not working on woocommerce please?

it use to work then suddenly it was not working, this morning I went to the setting to check if light box is enable I found it checked. After checking the site to find out it is still not working I went back to the setting and hahaha the light box has mysteriously vanished. A ghost in woocommerce?

Then I kept on trying reading all morning came back and when I want to go to setting again to see if the light box is back from his walk I find the cursor does not work on any link of the back end or on the site at the front end.

So much trouble in one morning is killing my self esteem and love for woocommerce. ??

I would really appreciate any help.

Thank you nice people
