Hi,
I am using BB with Genesis child theme (agency pro), when I link a photo to the light box it openes an Iframe but without the close button, this means you have no way to close the lightbox on an Ipad.
Any Idea
Hey Mohammed,
Welcome to the BB forums! 
You should be able to close the lightbox by clicking out of the popup image. Is that not the case for you?

Hi,
actually I was worried about the Ipad display, since the popup image fills the screen completely. But when trying it, surprisingly It shows a working close button I don’t have on a desktop screen.
Is this a normal behavior.
Hey Mohammed,
I actually tried playing around with this on my local dev and there is a close button at the top right corner of the popup image. This isn’t visible when the WP admin bar is there so you have to check the page logged out. Try visiting the our layouts page on the link below and you’ll see what I mean.
