Lightbox completely removed

hi there, I recently downloaded your plugin as i had changed the product image size on the product page but the lightbox was still the same size and i was hoping this plugin would help, but when i installed it and tried to use it to disable the lightbox it completely removed the product image, so i of course unticked the box and yet it still remained broken.

I have no clue what the issue is and really need a fix
