So, I have a lightbox video on the homepage of my store. When you click on it, the lightbox and video briefly appear and then the screen goes blank and turns all white. For the life of me, I can’t see what’s making this happen.

Any ideas?

This is code customization work!

Thanks!

Yes, that’s true. And thanks very much for your reply.

I’m not sure what you mean to say, I guess. Do you mean that this forum is inappropriate for that kind of question?
